Which one of the following statements regarding baking powder is NOT correct?
general-sciencechemistry
- AIt is a mixture
- BIt forms bubbles in a wet mixture
- CIt can be used instead of using yeast
- DIt does not contain sodium bicarbonate
Explanation
Baking powder is a mixture of sodium bicarbonate, an acid salt and starch; in a wet batter it releases carbon dioxide bubbles that leaven the dough, and it can substitute for yeast. The claim that it does not contain sodium bicarbonate is therefore false. Hence that statement is the one that is NOT correct.
