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 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. |
