Question

Reaction of hydrochloric acid with zinc oxide to form zinc chloride and water is a neutralization reaction.
A. True
B. False

Answer 1

Hint: Neutralization reaction is a chemical reaction in which an acid and a base react with each other to form salt and water.
Acid base neutralisation
${\text{Acid + Base}} \to {\text{Salt + Water}}$

Complete step by step answer: Neutralization reaction is a chemical reaction in which an acid and a base react with each other to form salt and water. In the reaction, ${{\text{H}}^{\text{ + }}}$ and ${\text{O}}{{\text{H}}^{\text{ - }}}$ions combine to form water. Salts formed in the reaction are the ionic compounds formed by an anion from an acid and a cation from a base.
Zinc oxide is represented by ${\text{ZnO}}$ and hydrochloric acid by ${\text{HCl}}$. Metal oxides are generally basic in nature, therefore, zinc oxide will act as a base. Hydrochloric acid will react with this basic metal oxide to neutralize each other. The products formed are zinc chloride represented by ${\text{ZnC}}{{\text{l}}_{\text{2}}}$ and water (${{\text{H}}_{\text{2}}}{\text{O}}$). Here zinc chloride is the respective salt formed by taking ${\text{Z}}{{\text{n}}^ + }$(cation) from ${\text{ZnO}}$(base) and ${\text{C}}{{\text{l}}^ - }$ (anion) from ${\text{HCl}}$ (acid). The reaction is as follows
${\text{Acid + Base}} \to {\text{Salt + Water}}$
${\text{2HCl + ZnO}} \to {\text{ZnC}}{{\text{l}}_{\text{2}}}{\text{ + }}{{\text{H}}_{\text{2}}}{\text{O}}$
Above reaction is neutralization reaction.
So, the correct answer is “Option A”.

Note: Remember that all the metal oxides are basic in nature as we have seen in the above example. Therefore if any of the metal oxide is allowed to react with any acid, the reaction will always be a neutralisation reaction.
