Question

In which reaction, hydrochoric acid is not behaving as an acid?
a) HCl(aq) + AgNO,(aq) -- AgCl(s) + HNO,(aq)
b) 2HCl(aq) + CaCO,(s) - CaCl2(aq) +H2O(l) + CO2
c) 2HCl(g) + Fe(s) - FeCl2(aq) + H2(g)
d) 6HCl(aq) + 2Fe - 2FeCl2(aq) + 3H2(g)​

Answer 1

Explanation:

Acids in aprotic solvents lose their acidic character due to decrease in their dissociation due to aprotic nature of solvents.

Because benzene is a non-polar solvent.

HCl will dissolve in it, but won’t ionize into Cl

−

and H

+

ions.

Answer 2

Hydrochloric acid does not behave as an acid when present in a gaseous state (Option c).

• According to the Bronsted Lowry theory of acid and base, acid is characterized by the fact that it gives proton (H⁺) under aqueous conditions.

• This can be represented chemically as:

        H₂O + HCl → H₃O⁺ + Cl⁻

• The dissociation H⁺ of acid takes place in the aqueous condition or when mixed with water.

• In the gaseous state, HCl behaves as dry hydrogen chloride and does not dissociate its ions.

• 2HCl(g) + Fe(s) - FeCl₂(aq) + H₂(g): The chemical equation signifies that  HCl is present in gas form.

• While in the rest of the chemical equations HCL is present in aqueous form and undergoes displacement reaction with the reactant.

• Hence we can conclude that hydrochloric acid does not behave as an acid if present as HCl(g).
