About Litmus Paper

Litmus paper comes in two colours: Red and Blue.

Litmus paper is a very simple indicator as it can only tell if something is acid or alkali but it cannot tell the exact pH of a solution.

Litmus paper cannot be used on a base unless it is in solution.

When red litmus is placed in an alkali it turns blue.


When red litmus is placed in an acid it stays red.	When red litmus is placed in an alkali it turns blue.	When red litmus is placed in a neutral solution it stays red.

When blue litmus is placed in an acid it turns red.	When blue litmus is placed in an alkali it stays blue.	When blue litmus is placed in a neutral solution it stays blue.
