Which acid is present in baking powder?
Think it through first, then pick an option.
- a Nitrous acid
- b Citric acid
- c Tartaric acid
- d Maleic acid
Answer and explanation
Correct answer: c Tartaric acid
Baking powder is baking soda (NaHCO₃) mixed with tartaric acid (C₄H₆O₆).
Why the other options are wrong
- a Nitrous acid: Baking powder has no nitrous acid; tartaric acid is mixed with the baking soda.
- b Citric acid: Citric acid is not the book's ingredient of baking powder; tartaric acid is mixed with baking soda.
- d Maleic acid: Maleic acid is not added to baking powder; tartaric acid is.
