CHEMICAL PROPERTIES of the phosphoric acid Functional Group as found in a weakly Acidic Aqueous Solution . In more Basic aqueous solutions, the group will donate the two Hydrogen Atom s and Ion ize as a phosphate group with a negative charge of 2. 1]] The phosphate ion is a Polyatomic ion with the Empirical Formula P O 43− and a Molar Mass of 94.973 g/mol; it consists of one central Phosphorus atom surrounded by four identical oxygen atoms in a Tetrahedral arrangement. The phosphate ion carries a negative three Formal Charge and is the Conjugate Base of the hydrogenphosphate ion, HPO42−, which is the conjugate base of H2PO4−, the dihydrogen phosphate ion, which in turn is the conjugate base of H3PO4, phosphoric acid. It is a Hypervalent Molecule (the phosphorus atom has 10 electrons in its Valence Shell ). '''Phosphate''' is also an Organophosphorus compound with the formula OP(OR)3 A phosphate salt forms when a positively charged ion attaches to the negatively charged oxygen atoms of the ion, forming an ionic Compound . Many phosphates are Insoluble in Water at Standard Temperature And Pressure , except for the Alkali Metal salts. In dilute aqueous solution, phosphate exists in four forms. In strongly basic conditions, the phosphate ion (PO43−) predominates, while in weakly basic conditions, the hydrogen phosphate ion (HPO42−) is prevalent. In weakly acid conditions, the '''dihydrogen phosphate''' ion (H2PO4−) is most common. In strongly acid conditions, aqueous phosphoric acid (H3PO4) is the main form. |
