give the formula for chromium (iii) hydrogen phosphate. click/scroll on the u button to get superscripts and subscripts.

Explanation:

Step1: Identify ion charges

Chromium(III) has a charge of $Cr^{3 +}$, and hydrogen phosphate has a charge of $HPO_{4}^{2 -}$.

Step2: Balance charges

To balance the charges, we need 2 chromium(III) ions and 3 hydrogen - phosphate ions.

Answer:

$Cr_{2}(HPO_{4})_{3}$
