Why can the sodium carbonate formed on heating baking soda cause a bitter taste?

Answer and explanation

Correct answer: Because sodium carbonate is basic in nature

On heating, baking soda decomposes according to 2NaHCO3 → Na2CO3 + H2O + CO2. The sodium carbonate left in the food is alkaline and can impart an unpleasant bitter or soapy taste when present in excess. Thus option A correctly identifies its basic nature. It is not a strong acid, a gas, or sugar, so options B, C, and D are chemically unsuitable.
