Answer 1

Juice of tamarind turns blue litmus to red. It is because of the presence of an acid called tartaric acid.

Explanation:

Natural foods contain naturally occurring acids, including tartaric, citric, and malic acids. Tartaric acid is a naturally occurring organic acid in several fruits, including tamarind. Due to its tartaric acid content, tamarind juice reacts with blue litmus paper, a pH indicator.
