Answer 2

Answer:

An acid that reacts with the ‘substance Z’ with the “liberation of $\mathrm{CO}_{2}$ gas”. The “nature of Z is base”

Explanation:

• A substance which dissolves in aqueous medium to produce “hydronium ions" are called acids.
• A substance which dissolves in aqueous medium to produce “hydroxide ions” are called bases.
• A substance which dissolved in aqueous media to produce equal volume of hydroxide and hydronium ions are called salts.
• If an acid that reacts with any substance to form $\mathrm{CO}_{2}$ gas they have carbonate group.
• For example: HCl reacts with sodium carbonate to form $\mathrm{CO}_{2}$ gas the reaction is as follows.

               $\mathrm{HCl}+\mathrm{Na}_{2} \mathrm{CO}_{3} \rightarrow \mathrm{NaCl}+\mathrm{H}_{2} \mathrm{O}+\mathrm{CO}_{2}$
