Why is a mild edible acid mixed with baking soda in baking powder?
Answer and explanation
Correct answer: To produce carbon dioxide in a controlled way
Baking soda is sodium hydrogen carbonate. It reacts with the edible acid in baking powder to form carbon dioxide, water, and a salt. The reaction is useful because carbon dioxide bubbles become trapped in the dough and make it rise, light, and soft. Option A is correct because the acid provides a controlled release of gas. It does not convert baking soda into metal, harden the dough, or produce chlorine.
