What will be the nature of sodium carbonate formed by heating baking soda?

Answer and explanation

Correct answer: Basic

Heating baking soda, sodium hydrogen carbonate, produces sodium carbonate, carbon dioxide, and water: 2NaHCO₃ → Na₂CO₃ + CO₂ + H₂O. Sodium carbonate is a salt of a strong base and a weak acid; its aqueous solution undergoes hydrolysis and contains excess hydroxide ions. Hence the solution, and the substance in the school-level sense asked here, is basic. Option A is correct; it is not acidic, neutral, or a description of metallic nature.
