Ph Locator Quezon Tayabas
In chemistry, pH (), historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or Base (chemistry), basicity of an aqueous solution. Acidic solutions (solutions with higher concentrations of Hydrogen ion#Cation (positively charged), ions) are measured to have lower pH values than basic or alkaline solutions. The pH scale is logarithmic scale, logarithmic and inversely indicates the concentration of Hydronium, hydrogen ions in the solution.Bates, Roger G. ''Determination of pH: theory and practice''. Wiley, 1973. :\ce = - \log(a_\ce) = -\log([\ce]/\ce M) where Molar concentration, M = mol dm−3. At 25 Celsius, °C (77Fahrenheit, °F), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at this temperature are neutral (i.e. have the same concentration of H+ ions as OH− ions, i.e. pure water). The neutral value of the pH depends on the temperaturebei ...
