Created: Aug 19, … The simplest example of this occurs in the reaction discussed earlier, in which hydrochloric acid or HCl( aq ) reacts with the base sodium hydroxide, designated as NaOH( aq ), in an aqueous solution. Reaction I. metal hydroxide + acid salt + water. The magnesium displaces the hydrogen from the acid. 2HCl + MgO → MgCl 2 + H 2 O. acids with metal hydroxides. #ZnCl_2(aq)# = zinc chloride salt dissolved in water You will probably remember that nitric acid reacts differently with metals from the other common acids.
