Lemon is a rich source of which acid?

Concept

Organic acids are naturally occurring carbon compounds that give many fruits their sour taste.

Different fruits characteristically contain different predominant organic acids, so the fruit must be matched with its commonly associated acid.

Application

Lemon is a citrus fruit. Citrus fruits contain abundant citric acid, which produces much of their characteristic sourness.

Contrast

• Malic acid is commonly associated with apples.

• Tartaric acid is classically associated with grapes and tamarind.

• Acetic acid is the principal acid in vinegar and is commonly formed through fermentation.

Result

Therefore, the acid for which lemon is a rich source is citric acid.
