Litmus paper is made from dyes derived from lichens; it is water-soluble, meaning it can be fully dissolved in water. Acids turn blue litmus paper red, and bases turn red litmus paper blue. The following video shows how red and blue litmus paper reacts to ammonia, hydrochloric acid, water, and .
Litmus paper is used as an acid-base indicator in chemical analysis. When litmus paper is placed in an acidic solution, it turns red. When placed in a basic solution, it turns blue. Chemists rely on this reaction to identify acidic or basic solutions. Although litmus paper is used to test for acidity, strong acid can just as well be used to test litmus paper. If a chemist were to place a strip of paper in a strongly acidic solution and it did not turn red, he would KNOW that the strip was not litmus paper. If a person who claimed to be a chemist were to insist that even though the paper did not turn red in strong acid, it is still genuine litmus paper, his judgment would be called into question. It would be apparent that he does not know chemistry. Litmus paper always reacts in a predictable fashion.
NOTE: Gasses react more rapidly with moist rather than dry litmus
