Concentration of the Ag+ ions in a saturated solution of Ag2C2O4 is 2.2×10-4 mol L-1. Solubility product of Ag2C2O4 is
  1. 2.42× 10-8
  2. 2.66×10-12
  3. 4.5×10-11
  4. 5.3×10-12

Solution

Ag2C2O4s⇌2Ag+aq+C2O42-aq2ss
Ksp=Ag+2 C2O42-
Ag+=2.2×10-4mol/L
∴     C2O42-=2.2×10-42 M=1.1×10-4M
∴      Ksp=2.2×10-42 1.1×10-4 (mol/L)3
=5.324×10-12 (mol/L)3.
