Question

Sodium metal reacts with Hydrochloric acid to produce salt and Hydrogen gas. What are the reactants in this chemical reaction?

Answer 1

The reaction of metal with an acid:-

• When a metal is put in an acid, it will get smaller and smaller as it is getting used up in the chemical reaction.
• And at that time of being consumed, there is the production of the gas bubbles as well as salt.
• The bubbles which are being produced in this reaction of metal getting consumed in and are of Hydrogen gas.
• And this can be proven by the usage of the burning splint as such Hydrogen is a flammable gas.
• The salt which is being produced depends upon the metal and acid which react.
• General equation:- $\mathrm{Acid}+\mathrm{Metal}\to \mathrm{Salt}+\mathrm{Hydrogen}$.
• Sodium metal reacts with Hydrochloric acid for the production of Hydrogen gas as well as the Sodium chloride salt.
• Reaction:- $\underset{\mathrm{Sodium}}{2\mathrm{Na}\left(\mathrm{s}\right)}+\underset{\mathrm{Hydrochloirc}\mathrm{acid}}{2\mathrm{HCl}\left(\mathrm{aq}\right)}\to \underset{\mathrm{Sodium}\mathrm{chloride}}{2\mathrm{NaCl}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}\mathrm{gas}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$.

Therefore, reactants in this chemical reaction are Sodium metal and Hydrochloric acid.
