Problem: Neutralization reaction between Mg(OH)2(s) and hydrochloric acid. Milk of magnesia is a suspension of water-insoluble magnesium hydroxide, Mg(OH)2(s), in water. When sufficient hydrochloric acid, HCl(aq), is added a reaction ensues that leads to an aqueous solution containing Mg2+(aq) and Cl-(aq) ions.If you used nitric acid instead of hydrochloric acid in this reaction, what products would form? Complete the balanced chemical formula.

Reactant

nitric acid → HNO3 (aq) → H+ (aq) + NO3- (aq)

magnesium hydroxide → Mg(OH)2(s) → Mg2+ (aq) + 2 OH- (aq)


product

H+ (aq) + OH- (aq) →  H2O (l)

Mg2+ (aq) + NO3- (aq) → Mg(NO3)2 → all nitrates are soluble → aqueous

Problem Details

Neutralization reaction between Mg(OH)2(s) and hydrochloric acid. Milk of magnesia is a suspension of water-insoluble magnesium hydroxide, Mg(OH)2(s), in water. When sufficient hydrochloric acid, HCl(aq), is added a reaction ensues that leads to an aqueous solution containing Mg2+(aq) and Cl-(aq) ions.

A series of photographs shows the overall reaction of the reactants Mg(OH)2 (solid) plus 2 HCl (aqueous) going to the products MgCl2 (aqueous) plus 2 H2O (liquid). In the first photograph, milk of magnesia (Mg(OH)2) is poured into a beaker, appearing opaque. In the second photograph, an aqueous solution of H+ and Cl- ions is added to the beaker.  H+ (aqueous) combines with hydroxide ions in Mg(OH)2 (solid), forming H2O (liquid). In the third photograph, the beaker appears mostly translucent, with H2O molecules and Mg2+ and Cl- ions in solution.
