Question

write the balanced dissociation equation for solid calcium phosphate in aqueous solution. if it does not dissociate, simply write only nr. be sure to include the proper phases for all species within the reaction.

Explanation:

Step1: Identify the formula of calcium phosphate

Calcium phosphate has the formula \(Ca_3(PO_4)_2\). Calcium has a charge of \(+2\) (\(Ca^{2+}\)) and phosphate has a charge of \(-3\) (\(PO_4^{3 -}\)).

Step2: Write the dissociation equation

When \(Ca_3(PO_4)_2\) dissociates in aqueous solution, it breaks into its constituent ions.

$$Ca_3(PO_4)_2(s) ightleftharpoons3Ca^{2 +}(aq)+2PO_4^{3 -}(aq)$$

Answer:

$$Ca_3(PO_4)_2(s) ightleftharpoons3Ca^{2 +}(aq)+2PO_4^{3 -}(aq)$$
