Which products are likely to form when sodium carbonate reacts with dilute acid?

Answer and explanation

Correct answer: Salt, water and carbon dioxide

The governing pattern for a metal carbonate reacting with an acid is acid + carbonate → salt + water + carbon dioxide. For example, Na₂CO₃ + 2HCl → 2NaCl + H₂O + CO₂. Thus option A lists all three products. Hydrogen belongs to the usual acid–metal reaction, whereas oxygen, a new metal, and a base are not expected products in this reaction.
