Question

How can the following be converted into the respective sulfate? Give equation.

(b) Magnesium

Answer 1

Reaction of metal and acid:

• A salt and hydrogen gas are produced when an acid undergoes a chemical reaction with a metal.
• When magnesium metal $\left(\mathrm{Mg}\right)$ reacts with sulfuric acid $\left({\mathrm{H}}_2{\mathrm{SO}}_4\right)$, then the formation of magnesium sulfate $\left({\mathrm{MgSO}}_4\right)$ and hydrogen gas $\left({\mathrm{H}}_2\right)$ takes place.

Chemical reaction:

• The chemical equation is as follows:

$\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{SO}}_4\left(\mathrm{aq}\right)\rightleftharpoons {\mathrm{MgSO}}_4+{\mathrm{H}}_2\left(\mathrm{g}\right)$
