The meaning of LITMUS is a coloring matter from lichens that turns red in acid solutions and blue in alkaline solutions and is used as an acid-base indicator.
alkaline solution, red litmus paper turns blue. When an alkaline compound dissolves in water, it produces hydroxide ions, which cause the solution to become alkaline. Red litmus paper can also be used to test the pH of a water-soluble gas by dampening the paper and exposing it to the gas...
