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.
A typical example such a reaction is what occurs when you equal amounts of a strong acid to a strong base. Hydrochloric acid, HCl, is a strong acid and sodium hydroxide, NaOH, is a strong base. When you mix the two in equal amounts, pure water (with a pH of 7) and table salt, NaCl are made.he reaction is: HCl(aq) + NaOH(aq) â NaCl(aq) + H2O(l) The net ionic reaction occurring here, and in most neutralization reactions is: H+ + OH- â H2O Note that this neutralization reaction can produce a tremendous amount of heat, and so can be quite dangerous!
