Chapter 13, Problem 49E

Additional solid silver sulfate, a slightly soluble solid, is added to a solution of silver ion and sulfate ion at equilibrium with solid silver sulfate.

${\text{2Ag}}^{+}+{\text{SO}}_{\text{4}}{}^{2-}\left(aq\right)\rightleftharpoons {\text{Ag}}_2{\text{SO}}_4\left(s\right)$

Which of the following will occur?

(a) Ag+ or SO₄²- concentrations will not change.

(b) The added silver sulfate will dissolve.

(c) Additional silver sulfate will form and precipitate from solution as Ag+ ions and SO₄²- ions combine.

(d) The Ag+ ion concentration will increase and the SO₄²- ion concentration will decrease.
