What is the reaction equation for Magnesium chloride and water?

When magnesium chloride (MgCl₂) dissolves in water, it dissociates into its constituent ions. The reaction can be represented as:

[ \text{MgCl}_2 (s) \rightarrow \text{Mg}^{2+} (aq) + 2 \text{Cl}^- (aq) ]

This equation shows that solid magnesium chloride breaks down into magnesium ions and chloride ions in aqueous solution.
