NEET2017ChemistryIonic EquilibriumActual
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
Options
- A2.42 × 10 - 8
- B2.66 × 10 - 12
- C4.5 × 10 - 11
- D5.3 × 10 - 12
Correct answer
D. 5.3 × 10 - 12
Step-by-step solution
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 .
