# What is the dissolution reaction for Ag_2SO_4. How many moles of ions are formed from it?

$A {g}_{2} {\left(S {O}_{4}\right)}_{2} \left(s\right) r i g h t \le f t h a r p \infty n s 2 A {g}^{+} + S {O}_{4}^{2 -}$
So 1 mol gives rise to 3 moles of ions GIVEN QUANTITATIVE DISSOLUTION. However, since silver sulfate is insoluble, you need details of ${K}_{s p}$, the solubility constant, before we quote solubilities.
