What is the value of \(\mathrm{K}_{\mathrm{sp}}\) for saturated solution of \(\mathrm{Ba}(\mathrm{OH})_2\) having pH 12 ?
- A \(4 \times 10^{-4}\)
- B \(4 \times 10^{-6}\)
- C \(5 \times 10^{-6}\)
- D \(5 \times 10^{-7}\)
Answer & Solution
Correct Answer
(D) \(5 \times 10^{-7}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{pOH} = 14 - \mathrm{pH} = 14 - 12 = 2\) \([\mathrm{OH}^-] = 10^{-\mathrm{pOH}} = 10^{-2}\ \mathrm{M}\)
