Ascorbic acid, also called vitamin C, is a white, odourless powder. It is easily soluble in water, soluble in ethanol and methanol and slightly soluble in acetone. Ascorbic acid and its sodium and calcium salts prevent the formation of free radicals.

Ascorbic acid is found in all living cells, but especially in fruits (e.g. lemons, oranges, sea buckthorn, rose hips) and vegetables (spinach, potatoes, peas).
