Answer- Let's start with the dissociation reaction of silver chromate:
Ag2CrO4 (s) 2Ag+ (aq) + CrO2-4 (aq)
Consider 'x' to be the molar solubility of the ions present in silver chromate.
So, Ksp can be written as,
Ksp = [2 Ag+]2 [ CrO2-4 ]
Ksp = (2x)2. x
Ksp = 4x3
Ksp = 8.96 x 10-12
x3 = 8.96 x 10-12 / 4
x3 = 2.24 x 10-12
On solving, we get = 1.30843 x 10-4 M 1.31 x 10-4 M
Thus, the correct option is 1.31 x 10-4M
