Question

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

Answer 1

`Ag_2(SO_4)_2(s) rightleftharpoons 2Ag^(+) + SO_4^(2-)`

Explanation:

So 1 mol gives rise to 3 moles of ions GIVEN QUANTITATIVE DISSOLUTION. However, since silver sulfate is insoluble, you need details of `K_(sp)`, the solubility constant, before we quote solubilities.
