Question

Red litmus paper turns what color in an acid

Answer 1

Answer: Litmus paper is a filter paper that has been treated with a natural water-soluble dye derived from lichen. As a result, a sheet of paper called "litmus paper" can be used as a pH indicator. Blue litmus paper turns red under acidic conditions (pH below 4.5), while red litmus paper turns blue under alkaline conditions (pH above 8.3). Blue litmus paper does not change color under alkaline conditions, while red litmus paper does not change color in acidic conditions. Neutral litmus paper has a reddish color. It turns red in an acidic environment and blue in an alkaline environment.
