The concentration of the A g + ions in a saturated solution of A g 2 C 2 O 4 is 2.2 × 1 0 - 4 m o l L - 1 . Solubility product of A g 2 C 2 O 4 is
Options
- A2.66 × 1 0 - 12
- B4.5 × 1 0 - 11
- C5.3 × 1 0 - 12
- D2.42 × 1 0 - 8
Correct answer
C. 5.3 × 1 0 - 12
Step-by-step solution
A g 2 C r O 4 ⇌ 2 A g + 2.2 × 1 0 - 4 m o l L - 1 + C r O 4 2 - 2.2 × 1 0 - 4 2 m o l L - 1 K s p = ( A g + ) 2 [ C r O 4 2 - ] = ( 2.2 × 1 0 - 4 ) 2 × 2.2 × 1 0 - 4 2 = 5.32 × 1 0 - 12
