Question
Which of the following statements is correct for a solution saturated with AgCl and AgBr if their solubilities in moles per litre in separate solutions are x and y respectively ?
Options
A.[Ag+] = x + y
B.[Ag+] = [Br-] + [Cl-]
C.[Br-] = y
D.[Cl-] > x.
Solution
AgCI ⇋ Ag+ + CI- AgBr ⇋ Ag+ + Br-
x x y y
(x + y) x (x + y) y
So [Ag+] = [Br-] + [CI–]
x x y y
(x + y) x (x + y) y
So [Ag+] = [Br-] + [CI–]
