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 25°C
C) Calculate the maximum mass , in grams , of Ag2CrO4 that can dissolve in 100ml of water at 25°C
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 25°C
G) A 1.00 L sample of saturated Ag3PO4 solution is allowed to evaporate at 25°C to a final volume of 500ml. What is [ Ag+] in the solution ? Justify your answer.
