Litmus paper is used as a pH indicator to determine whether the solution is acidic or basic. Substances with a pH level of 7 are neutral. Ones with a pH level below 7 are acidic. Ones with a pH above 7 are basic.
Litmus paper will work on pH principle. Litmus paper will have a colour coding so if want to dip onto some solution, it would change the colour depending on the pH.
There are 2 type of Litmus paper, 1) Red litmus paper and 2) Blue litmus paper.
It is red litmus paper (they are usually weak acids) turns blue when dipped in base and blue litmus paper (they are usually weak bases) turns red when dipped in acids.
Litmus paper (red and blue) is paper that has been treated with a specific indicator - a mixture of 10-15 natural dyes obtained from lichens (mainly Roccella tinctoria) that turns red in response to acidic conditions (pH < 7) and blue under alkaline conditions (pH > 7). When the pH is neutral (pH = 7) then the dye is purple.
