Phosphates are a group of chemical compounds related to phosphoric acid. These include salts containing the phosphate ion (PO₄³⁻), hydrogen phosphate ion (HPO₄²⁻), or dihydrogen phosphate ion (H₂PO₄⁻). Potassium dihydrogen phosphate, with the formula KH₂PO₄, falls into this category. It is used for controlling the hydrogen ion concentration (acidity) of solutions.21
