Solution

The correct option is C x+y=Ksp1+Ksp2

Simultaneous solubility:

Sparingly soluble salt 1: AB having x mol L1 solubility in the presence of AC

Sparingly soluble salt 2: AC having y mol L1 solubility in the presence of AB

AB(s) A+(aq)+B(aq) with Ksp1

Equilibrium:C1x x+y x

AC(s) A+(aq)+C(aq) with Ksp2

Equilibrium:C2y y+x y

From the above reactions the Ksp values are

Ksp1=(x)(x+y) (1)

Ksp2=(y)(x+y) (2)

Dividing both the equations

Ksp1Ksp2=xy

Adding both the equations

Ksp1+Ksp2=(x+y)2

x+y=Ksp1+Ksp2

Option A and option C are correct.
