Why does baking powder help cakes rise?
Answer and explanation
Correct answer: It releases carbon dioxide on heating
Baking powder generally contains sodium hydrogen carbonate and a suitable edible acid. When the mixture becomes moist and is heated, an acid-base reaction produces carbon dioxide; the gas bubbles expand and become trapped in the batter, making the cake rise. Option A is correct. The process does not convert oxygen into gold, make the dough completely acidic, or freeze water.
