Question

The solubility product of AgBr is \(4.9 \times 10^{-13}\) at a certain temperature. Calculate the molar solubility of AgBr.

• A. \(4 \times 10^{-6}\ \text{mol dm}^{-3}\)
• B. \(4 \times 10^{-7}\ \text{mol dm}^{-3}\)
• C. \(7 \times 10^{-7}\ \text{mol dm}^{-3}\)
• D. \(3 \times 10^{-8}\ \text{mol dm}^{-3}\)

Hint:

For salts of type \(AB\), \[ K_{sp} = s^2 \]
