What “litmus” means
Wiktionary · Wikipedialitmus/ˈlɪtməs/
- nounA dyestuff extracted from certain lichens, that changes color when exposed to pH levels greater than or less than certain critical levels.
Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often absorbed into filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. In an acidic medium, blue litmus paper turns red, while in a basic or alkaline medium, red litmus paper turns blue. In short, it is a dye and indicator which is used to place substances on a pH scale.
