Why is a mild acid mixed with baking soda in baking powder?
Answer and explanation
Correct answer: To help produce carbon dioxide
Baking powder contains baking soda and a mild edible acid. When the mixture becomes moist and is heated, the acid reacts with sodium hydrogen carbonate and releases carbon dioxide. The gas forms bubbles that expand during baking, making the dough or batter rise. Hence option A is correct; the reaction does not produce sodium metal or chlorine gas.
