A student investigates the rate of hydrolysis of haloalkanes. They mix 1-bromobutane with ethanol and aqueous silver nitrate, AgNO3(aq)\text{AgNO}_3(\text{aq})AgNO3(aq).
C4H9Br(l)+H2O(l)+Ag+(aq)→C4H9OH(aq)+H+(aq)+AgBr(s) \text{C}_4\text{H}_9\text{Br}(\text{l}) + \text{H}_2\text{O}(\text{l}) + \text{Ag}^+(\text{aq}) \rightarrow \text{C}_4\text{H}_9\text{OH}(\text{aq}) + \text{H}^+(\text{aq}) + \text{AgBr}(\text{s}) C4H9Br(l)+H2O(l)+Ag+(aq)→C4H9OH(aq)+H+(aq)+AgBr(s)During the reaction, the clear reactants are mixed together and the mixture gradually becomes cloudy.
Explain why the mixture turns cloudy.
