Question

How can the following be converted into the respective chlorides?

(b) Zinc.

Give the balanced chemical equation.

Answer 1

Reaction of metals and acid:

• A salt and hydrogen gas are produced when an acid undergoes a chemical reaction with a metal.
• When zinc metal $\left(\mathrm{Zn}\left(\mathrm{s}\right)\right)$ reacts with hydrochloric acid $\left(\mathrm{HCl}\left(\mathrm{aq}\right)\right)$, then formation of zinc chloride $\left({\mathrm{ZnCl}}_2\left(\mathrm{aq}\right)\right)$ and hydrogen gas $\left({\mathrm{H}}_2\left(\mathrm{g}\right)\right)$ takes place.

Chemical Reaction:

• The chemical equation is as follows:

$\mathrm{Zn}\left(\mathrm{s}\right)+2\mathrm{HCl}\left(\mathrm{aq}\right)\to {\mathrm{ZnCl}}_2\left(\mathrm{aq}\right)+{\mathrm{H}}_2\left(\mathrm{g}\right)$
