Which of the following reactants will come in place of A and give a neutralisation reaction? Ca(OH)2+A→ CaCl₂ + H₂O

AHydrochloric acid

BNitric acid

CSulphuric acid

DAcetic acid

Answer:

The reaction is a neutralization reaction between a base, Ca(OH)2(calcium hydroxide), and an acid.
The products are a salt, CaCl2(calcium chloride), and water, H2O.
To form CaCl2, the acid must contain Cl-.
Hydrochloric acid (HCl) is the only option that fits this requirement.
