What is the main benefit of adding a mild edible acid with baking soda in baking powder?
Answer and explanation
Correct answer: It reduces basic bitterness and helps produce carbon dioxide
Baking soda is sodium hydrogen carbonate, a mild base. If used alone, it may leave an unpleasant alkaline or bitter taste. The edible acid in baking powder reacts with it and produces carbon dioxide, for example: acid + NaHCO₃ → salt + water + CO₂. The gas bubbles expand during heating and make the batter rise, while the acid reduces the alkaline taste. Hence, option B is correct.
