$157.75\ \text{g}$ of bismuth(III) chloride, $\text{BiCl}_3$, is taken to prepare $500\ \text{cm}^3$ of solution with distilled water. When in water, the aqueous bismuth(III) chloride gradually turns cloudy because it reacts with water and produces insoluble bismuth oxychloride. This reaction is reversible. $\text{BiCl}_3\text{(aq)} + \text{H}_2\text{O(l)} \rightleftharpoons \text{BiOCl(s)} + 2\text{HCl(aq)}$ Which of the statements are correct? $[A_r:\ \text{Bi},\ 209;\ \text{Cl},\ 35.5]$
