Why may a cake not rise properly if baking powder has no mild acid?
Answer and explanation
Correct answer: The reaction producing carbon dioxide will be reduced
The governing concept is the acid–carbonate reaction used in baking. Baking powder contains baking soda and a mild edible acid. When moistened and heated, the acid reacts with sodium hydrogen carbonate and releases CO₂, whose bubbles expand and make the batter rise. Without enough acid, less CO₂ is produced, so option A is correct; chlorine formation, salt conversion, and metallic water are irrelevant.
