Question

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

Ag 2 C 2 O 4 s ⇌ 2 Ag + aq + C 2 O 4 2 - aq 2 s s K sp = Ag + 2 C 2 O 4 2 - Ag + = 2 .2 × 10 - 4 mol / L ∴ C 2 O 4 2 - = 2 .2 × 10 - 4 2 M = 1 .1 × 10 - 4 M ∴ K sp = 2 .2 × 10 - 4 2 1 .1 × 10 - 4 ( mol / L ) 3 = 5 .324 × 10 - 12 ( mol / L ) 3 .
