Question

State whether true or false:

Hydrogen gas is liberated when Magnesium reacts with dilute Hydrochloric acid.

• A. True
• B. False

Answer 1

The correct option is A True

• The reaction occurs between Magnesium ribbon and dilutes Hydrochloric acid to form Magnesium chloride and Hydrogen gas.
• In such a reaction Magnesium works as a reducing agent while Hydrogen is an oxidizing agent.
• The chemical reaction occurs as follows: $\underset{\left(\mathrm{Magnesium}\right)}{\mathrm{Mg}\left(\mathrm{s}\right)}+\underset{(\mathrm{Hydrogen}\mathrm{chloride})}{2\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{(\mathrm{Magnesium}\mathrm{chloride})}{{\mathrm{MgCl}}_2\left(\mathrm{s}\right)}+\underset{(\mathrm{Hydrogen}\mathrm{gas})}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
• Thus, Hydrogen is liberated in such a process.
• Therefore, the given statement is true.
