Magnesium Phosphate Tribasic
Trimagnesium phosphate is a compound with formula Mg3(PO4)2. It is a magnesium acid salt of phosphoric acid. It can be formed by reaction of stoichiometric quantities of monomagnesium phosphate with magnesium hydroxide.Mg(H2PO4)2+2 Mg(OH)2→Mg3(PO4)2•8H2O [1]Found in nature in octohydrate form as the mineral bobierrite.[2] The anhydrous compound is isostructural with cobalt(II) phosphate. The metal ions occupy both octahedral (six-coordinate) and pentacoordinate sites in a 1:2 ratio.[3]Safety[edit] Magnesium phosphate

Magnesium Sulfide
Magnesium
Magnesium
sulfide is an inorganic compound with the formula MgS. It is a white crystalline material but often is encountered in an impure form that is brown and non-crystalline powder. It is generated industrially in the production of metallic iron.Contents1 Preparation and general properties 2 Applications 3 Occurrence 4 Safety 5 ReferencesPreparation and general properties[edit] MgS is formed by the reaction of sulfur or hydrogen sulfide with magnesium. It crystallizes in the rock salt structure as its most stable phase, its zinc blende[1] and wurtzite[2] structures can be prepared by Molecular Beam Epitaxy. The chemical properties of MgS resemble those of related ionic sulfides such as those of sodium, barium, or calcium. It reacts with oxygen to form the corresponding sulfate, magnesium sulfate

Phosphoric Acid
Phosphoric acid
Phosphoric acid
(also known as orthophosphoric acid or phosphoric(V) acid) is a mineral (inorganic) and weak acid having the chemical formula H3PO4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound. The prefix ortho- is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids. Orthophosphoric acid is a non-toxic acid, which, when pure, is a solid at room temperature and pressure. The conjugate base of phosphoric acid is the dihydrogen phosphate ion, H 2PO− 4, which in turn has a conjugate base of hydrogen phosphate, HPO2− 4, which has a conjugate base of phosphate, PO3− 4

Water
Water
Water
is a transparent, tasteless, odorless, and nearly colorless chemical substance that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Strictly speaking, water refers to the liquid state of a substance that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity. Water

Octahedral Molecular Geometry
In chemistry, octahedral molecular geometry describes the shape of compounds with six atoms or groups of atoms or ligands symmetrically arranged around a central atom, defining the vertices of an octahedron. The octahedron has eight faces, hence the prefix octa. The octahedron is one of the Platonic solids, although octahedral molecules typically have an atom in their centre and no bonds between the ligand atoms. A perfect octahedron belongs to the point group Oh. Examples of octahedral compounds are sulfur hexafluoride SF6 and molybdenum hexacarbonyl Mo(CO)6. The term "octahedral" is used somewhat loosely by chemists, focusing on the geometry of the bonds to the central atom and not considering differences among the ligands themselves
