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.
The reverse of the neutralization reaction is called hydrolysis. In a hydrolysis reaction a salt reacts with water to yield the acid or base: BA + H 2 O â HA + BOH. More specifically, there are four combinations of strong and weak acids and bases: 1  strong acid + strong base, e.g., HCl + NaOH â NaCl + H 2 O.he reaction between a strong acid and a weak base also produces a salt, but water is not usually formed because weak bases tend not to be hydroxides. In this case, the water solvent will react with the cation of the salt to reform the weak base.
