Baking powder is a mixture of baking soda (sodium hydrogen carbonate) and ______?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Tartaric Acid
Baking powder is a mixture of baking soda (sodium hydrogen carbonate) and a mild edible acid such as tartaric acid. When it is heated or mixed with water, the acid reacts with the baking soda and gives off carbon dioxide, which makes bread and cakes rise and turn soft and spongy. The acid also removes the bitter taste that sodium carbonate, left from baking soda alone, would give.
