An active metal is a metal that displaces hydrogen from an acid. Examples of active metals include magnesium, zinc and iron. This type of reaction is also called a single displacement reaction where the active metal 'displaces' the hydrogen from the acid. Examples of reactions involving acids and active metals. 1  Hydrochloric acid + Magnesium â Magnesium chloride + Hydrogen.
An acid plus an alkali makes a salt plus water. Hydrochloric acid makes chlorides. Sulfuric acid makes sulfates. Nitric acid makes nitrates. This is the balanced chemical equation for the reaction of hydrochloric acid and sodium hydroxide.hydrochloric acid + sodium hydroxide sodium chloride + water. HCl(aq) + NaOH(aq) NaCl(aq) + H2O(l). This is the balanced chemical equation for the reaction of sulfuric acid and potassium hydroxide.sulfuric acid + potassium hydroxide potassium sulfate + water. H2SO4(aq) + 2KOH(aq) K2SO4(aq) + 2H2O(l). When ammonia is used as the alkali, ammonium hydroxide is formed in solution.ulfuric acid makes sulfates. Nitric acid makes nitrates. This is the balanced chemical equation for the reaction of hydrochloric acid and sodium hydroxide. hydrochloric acid + sodium hydroxide sodium chloride + water.
