How does baking powder help food rise?
Answer and explanation
Correct answer: By producing 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 expands and forms bubbles in the dough or batter; these bubbles make the food rise and become porous. Hydrogen, chlorine, and nitrogen are not the gases produced, so option A is correct.
