The maximum solubility of silver sulfate, Ag2SO4 [molar mass = 312], is 4.50 g/L at 25C. Silver sulfate dissociates by the reaction below:

Ag2SO4(s) <--> 2 Ag+ (aq)+ SO4 (aq)

1.What are the [Ag+] and [SO4] in a saturated solution of silver sulfate made by dissolving excess solid in distilled water at 25C?

2.Write the Ksp expression for silver sulfate and calculate its value at 25C.

3.Will precipitation of silver sulfate occur if 0.100 mol of silver ions are added to 2500.0 ml of 0.100M sulfuric acid, H2SO4 ? Show calculations to support your conclusion.
