Question

If salt AB = A + B having solubility 0.001g/dm3.if the Molar mass of AB is 100 amu. Find its solubility product?​

Answer 1

Answer:

Correct option is

B

10−4M

For a saturated solution Ksp=[A+][B−]

10−8=[10−3][B−]

[B−]=10−5

The precipitation will occur when Qsp is greater than Ksp and it will possible when [B−]<10−5.

Only option (b) is correct.
