MCQ
The saturated solution of $A{g_2}S{O_4}$ is $2.5 \times {10^{ - 2}}\,M.$ Its solubility product $({K_{sp}})$ is
- ✓$62.5 \times {10^{ - 6}}$
- B$6.25 \times {10^{ - 4}}$
- C$15.625 \times {10^{ - 6}}$
- D$3.125 \times {10^{ - 6}}$
✓
Answer
Correct option: A.
$62.5 \times {10^{ - 6}}$
(a)${K_{sp}} = 4{s^3} = 4 \times {[2.5 \times {10^{ - 2}}]^3} = 62.5 \times {10^{ - 6}}$.
