Question

Complete and balance the following equations:

$\mathrm{Al}+6\mathrm{HCl}\to$

Answer 1

The metals above hydrogen in the reactivity series have the potency to be attacked by acids. As a result of the reaction, hydrogen gas is liberated and the corresponding salts are formed.

Aluminium (Al) metal reacts with Hydrochloric acid (HCl) and displays a displacement reaction in which Hydrogen from HCl gets displaced by Aluminium and forms Aluminium chloride $\left({\mathrm{AlCl}}_3\right)$.

The complete and balanced equation is given as:

$$\begin{gathered} 2\mathrm{Al}\left(\mathrm{s}\right)+6\mathrm{HCl}\left(\mathrm{aq}\right)\to 2{\mathrm{AlCl}}_3\left(\mathrm{aq}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right) \\ \mathrm{Aluminium}\mathrm{Hydrochloric}\mathrm{Aluminium}\mathrm{Hydrogen}\mathrm{gas} \\ \mathrm{acid}\mathrm{chloride} \end{gathered}$$
