Answer:
Litmus is extracted from lichens
Litmus is a solution of different dyes made from lichen. This is then put onto filter paper. The paper can then be used to give a rough indication of the pH value of a solution. Blue litmus paper will turn red, when acid is present; red litmus paper will turn blue when alkalines are present.
