A weak base is \(5 \%\) dissociated in its 0.01 M solution. Calculate the dissociation constant.
- A \(3.5 \times 10^{-6}\)
- B \(2.0 \times 10^{-5}\)
- C \(2.3 \times 10^{-4}\)
- D \(2.5 \times 10^{-5}\)
Answer & Solution
Correct Answer
(D) \(2.5 \times 10^{-5}\)
Step-by-step Solution
Detailed explanation
\(\alpha = 5 \% = 0.05\) \(K_b = C \alpha^2 = (0.01)(0.05)^2 = 2.5 \times 10^{-5}\)
