How does baking powder help food rise?
Answer and explanation
Correct answer: By producing carbon dioxide
Baking powder contains sodium hydrogen carbonate along with a mild edible acid. When the mixture becomes moist and is heated, the acid reacts with the bicarbonate and releases carbon dioxide gas. The gas gets trapped as bubbles in the dough or batter; on heating, these bubbles expand and make the food rise. Hydrogen, chlorine, and nitrogen are not the gases responsible for this leavening action.
