the Netherlands

, particularly Lecanora tartarea and Roccella tinctorum.

How many types of litmus paper are there?

There are

two types

of litmus paper: red and blue. Red litmus paper is used to check for basicity (red paper turns blue when exposed to bases), and blue litmus paper is used to check for acidity (blue paper turns red when exposed to acids).

How is litmus solution formed?

Litmus solution is

extracted from lichens

. Lichens are plants belonging to the Thallophyta group. The process of obtaining litmus solution needs the crushing and grinding of lichens. These dyes are then added to neutral water to get the required litmus solution.

What turns red litmus into blue?

Red litmus contains a weak diprotic acid. When it is exposed to a basic compound, the hydrogen ions react with the added base. The

conjugate base formed from

the litmus acid has a blue color, so the wet red litmus paper turns blue in alkaline solution.
