What is in litmus paper that makes it turn red when dipped in a acid?
Litmus paper is a commonly used pH indicator. Litmus is a water-soluable mixture of dyes extracted from lichens. When the paper is dipped into an acidic solution, the paper absorbs a proton from the acidic solution, and it creates a new compound inside the paper that absorbs lower energy light (red light). This makes the paper appear red.
