# A student prepares a saturated aqueous solution of aluminum hydroxide, \(\text{Al(OH)}_3\), at \(25\text{ }^\circ\text{C}\). The dissolution equilibrium is represented by the equation below.

\[ \text{Al(OH)}_3\text{(s)} \rightleftharpoons \text{Al}^{3+}\text{(aq)} + 3\text{ OH}^-\text{(aq)} \]

If \(s\) represents the molar solubility of \(\text{Al(OH)}_3\) in \(\text{mol/L}\), which of the following expressions correctly represents the solubility product constant, \(K_{sp}\), in terms of \(s\)?

If \(s\) represents the molar solubility of \(\text{Al(OH)}_3\) in \(\text{mol/L}\), which of the following expressions correctly represents the solubility product constant, \(K_{sp}\), in terms of \(s\)?

- **A.** \(K_{sp} = s^4\)
- **B.** \(K_{sp} = 27s^4\)
- **C.** \(K_{sp} = 3s^4\)
- **D.** \(K_{sp} = 3s^2\)
