Question

3. Assertion : In water, Hydrochloric acid behaves as a weak monobasic acid.
Reason: In water, Hydrochloric acid acts as a proton donor.​

Answer 1

The assertion is wrong but the reason is correct.

• Hydrochloric acid is a strong acid in water. Hydrochloric acid is completely ionized in aqueous solutions.

• Hydrochloric acid is a proton donor if we added hydrochloric acid to water it will donate its proton to water.

• Hydrochloric acid produces chloride ions in the ionization process.

• HCl( hydrochloric acid) completely dissolved in water it produces positively charged hydrogen ions and negatively charged chloride ions.

Answer 2

Assertion is false but the reason is TRUE

Explanation:

Hydrochloric acid, HCl, fully ionize completely in aqueous solution as it is a strong acid.

In other words, each molecule of hydrochloric acid added to the water releases its proton H + into a molecule of water to form a hydronium cation H3O +. Thus, it acts as a proton donor in the water.

Ionization of hydrochloric acid also creates chloride anions, Cl−.

This means that the chemical equation describing hydrochloric acid ionization looks like this

HCl(aq) + H2O(l) → H3O+(aq) + Cl–(aq)

Note that each mole of ionizing hydrochloric acid produces 1 mole of hydronium cations and 1 mole of chloride anions.
