Answer

Explanation:

Step1: Determine the charges of the ions

Calcium ion ((Ca^{2+})) has a charge of (+2). Hydrogen phosphate ion ((HPO_{4}^{2 -})) has a charge of (-2).

Step2: Use the criss - cross method

The charges of the ions are (+2) and (-2). When using the criss - cross method (where the magnitude of the charge of one ion becomes the subscript of the other ion), (\frac{Ca^{2+}}{HPO_{4}^{2 -}}), the (2) from (Ca^{2+}) and the (2) from (HPO_{4}^{2 -}) cancel each other out.

Answer:

(CaHPO_{4})
