The balanced chemical equation for the reaction between phosphate rock (Ca3(PO4)2) and acid to produce soluble phosphate ions (H2PO4-) is:

Ca3(PO4)2 + 2H+ → 2HPO4- + 3Ca2+

From this equation, we can determine the stoichiometric ratios.

1 mole of phosphate rock (Ca3(PO4)2) reacts with 2 moles of acid (H+) to produce 2 moles of soluble phosphate ions (HPO4-) and 3 moles of calcium ions (Ca2+).

Therefore, the stoichiometric ratios for the conversion are as follows:

1 mol Ca3(PO4)2 : 2 mol H+
1 mol Ca3(PO4)2 : 2 mol HPO4-
1 mol Ca3(PO4)2 : 3 mol Ca2+
