Electrolyte
An electrolyte is a medium containing ions that is electrically conducting through the movement of those ions, but not conducting electrons. This includes most soluble salts, acids, and bases dissolved in a polar solvent, such as water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent. Solid-state electrolytes also exist. In medicine and sometimes in chemistry, the term electrolyte refers to the substance that is dissolved. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current. Some gases, such as hydrogen chloride (HCl), under conditions of high temperature or low pressure can also function as electrolytes. El ...

Solid-state Electrolyte
A solid-state electrolyte (SSE) is a solid Ionic conductivity (solid state), ionic conductor and electron-insulating electrolyte, material and it is the characteristic component of the solid-state battery. It is useful for applications in electrical energy storage (EES) in substitution of the liquid electrolytes found in particular in lithium-ion battery. The main advantages are the absolute safety, no issues of leakages of toxic organic liquid, organic solvents, low flammability, non-volatility, mechanical and thermal stability, easy processability, low self-discharge, higher achievable power density and cyclability. This makes possible, for example, the use of a lithium metal anode in a practical device, without the intrinsic limitations of a liquid electrolyte thanks to the property of lithium dendrite suppression in the presence of a solid-state electrolyte membrane. The utilization of a high capacity anode and low reduction potential, like lithium with a specific capacity of 38 ...

Conductivity (electrolytic)
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is Siemens per meter (S/m). Conductivity measurements are used routinely in many industrial and environmental applications as a fast, inexpensive and reliable way of measuring the ionic content in a solution. For example, the measurement of product conductivity is a typical way to monitor and continuously trend the performance of water purification systems. In many cases, conductivity is linked directly to the total dissolved solids (TDS). High quality deionized water has a conductivity of about 0.05 μS/cm at 25 °C, typical drinking water is in the range of 200–800 μS/cm, while sea water is about 50 mS/cm ncorrect according to source(or 50,000 μS/cm). Conductivity is traditionally determined by connecting the electrolyte in a Wheatstone bridge. Dilute solutions follow Kohlrausch's Laws of concentrat ...

Suero Oral
In the United States, Suero Oral® is a brand name of an electrolyte solution used to re-hydrate after working in heat-intensive environments, athletic activity, to treat pediatric vomiting and diarrhea, and as a hangover remedy. The product is similar in formula to other popular pediatric electrolyte beverages such as Pedialyte®. The name originated as a reference to suero casero, a whey-based home remedy (also known simply as suero) given to children in parts of South and Central America, the Caribbean, and other Spanish speaking areas. These homemade solutions are common to many households and used to combat dehydration caused by illness, work in extreme heat, or by certain diseases. Oftentimes, in these regions, these homemade solutions are referred to casually as ''suero casero'' (homemade serum), or ''sueros'', but this usage has not extended to the United States. In the United States, the product Suero Oral® contains a blend of water with sugars, flavoring agents (e.g. l ...

Chloride
The chloride ion is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents. Chloride salts such as sodium chloride are often very soluble in water.Green, John, and Sadru Damji. "Chapter 3." ''Chemistry''. Camberwell, Vic.: IBID, 2001. Print. It is an essential electrolyte located in all body fluids responsible for maintaining acid/base balance, transmitting nerve impulses and regulating liquid flow in and out of cells. Less frequently, the word ''chloride'' may also form part of the "common" name of chemical compounds in which one or more chlorine atoms are covalently bonded. For example, methyl chloride, with the standard name chloromethane (see IUPAC books) is an organic compound with a covalent C−Cl bond in which the chlorine is not an anion. Electronic properties A chloride ion (diameter 167  pm) is much larger tha ...

Anorexia Nervosa
Anorexia nervosa, often referred to simply as anorexia, is an eating disorder characterized by low weight, food restriction, body image disturbance, fear of gaining weight, and an overpowering desire to be thin. ''Anorexia'' is a term of Greek origin: ''an-'' (ἀν-, prefix denoting negation) and ''orexis'' (ὄρεξις, "appetite"), translating literally to "a loss of appetite"; the adjective ''nervosa'' indicating the functional and non-organic nature of the disorder. ''Anorexia nervosa'' was coined by Gull in 1873 but, despite literal translation, the feeling of hunger is frequently present and the pathological control of this instinct is a source of satisfaction for the patients. Individuals with anorexia nervosa have a fear of being overweight or being seen as such, although they are in fact underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". In research and clinical settings, thi ...

Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin ''kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac- colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, ...

Bulimia
Bulimia nervosa, also known as simply bulimia, is an eating disorder characterized by binge eating followed by purging or fasting, and excessive concern with body shape and weight. The aim of this activity is to expel the body of calories eaten from the binging phase of the process. Binge eating refers to eating a large amount of food in a short amount of time. Purging refers to the attempts to get rid of the food consumed. This may be done by vomiting or taking laxatives. Other efforts to lose weight may include the use of diuretics, stimulants, water fasting, or excessive exercise. Most people with bulimia are at a normal weight. The forcing of vomiting may result in thickened skin on the knuckles, breakdown of the teeth and effects on metabolic rate and caloric intake which cause thyroid dysfunction. Bulimia is frequently associated with other mental disorders such as depression, anxiety, borderline personality disorder, bipolar disorder and problems with drugs or alcohol. ...

Anion
An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is a negatively charged ion with more electrons than protons. Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and ...

Salt (chemistry)
In chemistry, a salt is a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions, which results in a compound with no net electric charge. A common example is table salt, with positively charged sodium ions and negatively charged chloride ions. The component ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (). Types of salt Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called ''alkali salts'' and salts that produce hydrogen ions when dissolved in water are called ''acid salts''. ''Neutral salts'' are those salts that are neither acidic nor basic. Zwitterions contain an anionic and a cationic centre in the same molecule, but are not considered salts. Examples of zwitterions are amino acids, many metabolites, peptid ...

Sports Drink
Sports drinks, also known as electrolyte drinks, are functional beverages whose stated purpose is to help Sportsperson, athletes replace water, electrolytes, and energy before, during and especially after training or competition. There are many perceived benefits and questions pertaining to the efficacy of use for sports and fitness performance. At times if used too much, in wrong cases (as most of nutritional items) they may hinder health or performance. The drinks, or some of their ingredients such as sugar, may not be suitable for certain conditions. Categories of sport drinks Sports drinks can be split into three major types: *Tonicity#Isotonicity, Isotonic sport drinks contain similar concentrations of salt and sugar as in the human body. *Tonicity#Hypertonic solution, Hypertonic sport drinks contain a higher concentration of salt and sugar than the human body. *Tonicity#Hypotonicity, Hypotonic sport drinks contain a lower concentration of salt and sugar than the human body ...

Pedialyte
Pedialyte is an oral electrolyte solution manufactured by Abbott Laboratories and marketed for use in children. It was invented by Dr. Gary Cohen of Swampscott, Massachusetts. Description Pedialyte is designed to promote rehydration and electrolyte replacement in ill children. It "meets the requirements of the American Academy of Pediatrics (AAP) Committee on Nutrition to help prevent dehydration in infants and children." Pedialyte is lower in sugars than most sports drinks, containing 100 calories per liter compared to approximately 240 in Gatorade. It contains more sodium (1,035 milligrams per liter vs. 465 mg/L in Gatorade) and potassium (780 milligrams per liter vs. 127 mg/L in Gatorade). Pedialyte does not contain sucrose, because this sugar has the potential to make diarrhea worse by drawing water into the intestine, increasing the risk of dehydration. In its flavored formulations, Pedialyte uses the synthetic sweeteners sucralose and acesulfame potassium. Pedialyte ha ...
