solubility of silver compounds

Answer the following questions relating to the solubilities of two silver compounds. Ag2CrO4 and Ag3PO4

Silver chronate dissociates in water according to the equation shown below

Ag2CrO4 (s). = 2 Ag+ (aq) + CrO4 2- (aq)
Ksp = 2.6 x 10^-12 at 25C

A) write the equilibrium constant expression for the dissolving of Ag2CrO4 (s)

B). Calculate the concentration , in mol/L , of Ag+ (aq) , in a saturated
solution of Ag2CrO4 at 25C

C) calculate the maximum mass , in grams , of Ag2CrO4 that can dissolve in 100ml
of water at 25C

D) A 0.100 mol sample of solid AgNO3 is added to a 1.00 L saturated solution of
Ag2CrO4. Assuming no volume change does [CrO4 - ] increase , decrease or remain
the same. Justify your answer

In a saturated solution of Ag3PO4 at 25C , the concentration of Ag+ (aq) is 5.3
x 10^-5 M. The equilibrium- constant expression for the dissolving of Ag3PO4 (s)
in water is
Ksp = [Ag+ ] ^3 [PO4 3- ]

E) write the balanced equation for the dissolving of Ag3PO4 (s) in water

F) Calculate the value of Ksp for Ag3PO4 (s) at 25C

G) A 1.00 L sample of saturated Ag3PO4 solution is allowed to evaporate at 25C
to a final volume of 500ml.
What is [ Ag+] in the solution ? Justify your answer
