Baking powder is a chemical leavening agent that is a mixture of a base (typically sodium bicarbonate, NaHCO₃, also known as baking soda), a weak acid (such as cream of tartar, sodium aluminium sulfate, or monocalcium phosphate), and sometimes a starch filler. Statement D claims that baking powder does not contain sodium bicarbonate, which is false.
Sodium bicarbonate is a fundamental component of baking powder. When moistened, the acid and sodium bicarbonate react to produce carbon dioxide gas, which creates bubbles (leavening) in doughs and batters.
Options A, B, and C are correct statements about baking powder. A) It is a mixture of different chemical compounds. B) The reaction upon wetting produces carbon dioxide bubbles. C) It is used as an alternative leavening agent to yeast, providing a quicker rise without fermentation.
