Introduction:
Tartaric acid is a white crystalline organic acid that occurs naturally in many plants, most notably in grapes.

It is commonly mixed with sodium bicarbonate and is sold as baking powder used as a leavening agent in food preparation. The acid itself is added to foods as an antioxidant and to i***rt its distinctive sour taste.
