Baking powder is a mixture of baking soda and a mild edible acid such as
A
Acetic acid
B
Benzoic acid
C
Hydrochloric acid
D
Tartaric acid
Correct Option:
D
Explanation
Baking powder is mainly a mixture of baking soda, sodium hydrogen carbonate, and a mild edible acid such as tartaric acid. When moisture and heat are supplied, the acid reacts with baking soda and releases carbon dioxide, which makes cakes and breads rise. Hydrochloric acid is far too corrosive, while benzoic acid is mainly used as a preservative.
