Magnesium chloride can also be made by reacting magnesium oxide with dilute hydrochloric acid.
MgO(s) + 2HCl(aq) → MgCl2(aq) + H2O(l)
(i) Write the ionic equation, including state symbols, for this reaction
A further method for making magnesium chloride is by reacting magnesium carbonate with dilute hydrochloric acid.
MgCO3(s) + 2HCl(aq) → MgCl2(aq) + H2O(l) + CO2(g)
