Which one of the following acids is used in the manufacturing of baking powder ?

Oxalic acid
Lactic acid
Tartaric acid
Benzoic acid

The correct answer is (c), tartaric acid.

Tartaric acid is a naturally occurring weak acid found in many fruits and vegetables, including grapes, raspberries, and tamarind. It is also produced commercially by fermentation of grape juice. Tartaric acid is used in a variety of applications, including baking powder, winemaking, and candy making.

Oxalic acid is a strong acid that is found in many plants, including rhubarb and spinach. It is also produced commercially by the oxidation of oxalic ore. Oxalic acid is used in a variety of applications, including cleaning, metal polishing, and tanning leather.

Lactic acid is a weak

acid that is produced naturally by the fermentation of sugars. It is also produced commercially by the fermentation of milk. Lactic acid is used in a variety of applications, including food production, cosmetics, and pharmaceuticals.

Benzoic acid is a weak acid that is found in many plants, including cloves and cinnamon. It is also produced commercially by the oxidation of toluene. Benzoic acid is used in a variety of applications, including food preservation, cosmetics, and pharmaceuticals.

In baking powder, tartaric acid reacts with baking soda to produce carbon dioxide gas. This gas causes the batter to rise.
