Which potassium acid salt is obtained as a by-product of alcohol manufacture during the fermentation process?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Potassium bitartrate.
The potassium acid salt obtained as a by-product of alcohol manufacture during the fermentation process is potassium bitartrate, commonly known as cream of tartar. It forms when potassium is present in grape juice or other fermentable materials during the fermentation process, reacting with tartaric acid. This salt crystallizes out of the solution and is collected as a by-product. Potassium bitartrate has various culinary uses, such as stabilizing egg whites and cream, and is also used in baking powders.
