Reversible reactions and equilibrium — practice question

When bismuth(III) chloride, $\text{BiCl}_3$, reacts with water, white bismuth(III) oxychloride, $\text{BiOCl}$, is produced. The reaction is represented by the equation. $\text{BiCl}_3\text{(aq)} + \text{H}_2\text{O(l)} \rightleftharpoons \text{BiOCl(s)} + 2\text{H}^+\text{(aq)} + 2\text{Cl}^-\text{(aq)}$. This reaction is in equilibrium. Which changes make the white precipitate dissolve?

  • A1 and 2 only
  • B1 and 3 only
  • C2 and 3 only
  • D1, 2 and 3
