NEET Chemistry pH & Buffer Solutions MCQ Question

Type: MCQ-numerical-Medium-Class 11

Calculate the solubility product constant (Ksp) for barium sulfate (BaSO4) if the concentration of Ba2+ in a saturated solution is 1.0 x 10^-5 M.

A

0 x 10^-10

B

0 x 10^-15

C

0 x 10^-20

D

0 x 10^-25

Correct Answer

Option A

Detailed Explanation

The solubility product constant Ksp is calculated using the formula Ksp = [Ba2+][SO4 2-]. Given [Ba2+] = 1.0 x 10^-5 M, and because BaSO4 dissociates into one Ba2+ and one SO4 2-, [SO4 2-] is also 1.0 x 10^-5 M. Therefore, Ksp = (1.0 x 10^-5)(1.0 x 10^-5) = 1.0 x 10^-10.
