Question

Concentration of the Ag+ ions in a saturated solution of Ag2C2O4 is 2.2 ×10-4 mol L-1 Solubility product of Ag2C2O4 is :-

Options

A.

2.66 ×10-12

B.

4.5 ×10-11

C.

5.3 ×10-12

D.

2.42 ×10-8

Solution

Ag2C2O4 ⇌ 2Ag+    +    C2O42-              2.2×10-4 M          1.1 ×10-4M
Ksp = [Ag+]2[C2O42-]
= [2.2 × 10-4]2. [1.1 ×10-4]
Ksp = 5.3 ×10-12
