Question

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

• A. Hydrochloric acid
• B. Nitric acid
• C. Sulphuric acid
• D. Acetic acid

Answer 1

Answer:

A. Hydrochloric acid

• 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.
