Litmus is a colored powder, obtained from certain lichens, that changes to red in an acid solution, and to blue in an alkaline solution. Litmus is a mixture of various closely related heterocyclic organic compounds. It is used to make litmus paper , which can be used to determine whether a solution is basic or acidic by dipping a strip of the paper into the solution and seeing how the paper changes color.

∙ 15y agoIt's a test to determine the acidity of a substance, usually a liquid. Sometimes also used out of context to describe a test, or a taxing situation considered to bring out or expose the true qualities of something. Seeing whether it can scratch glass could be considered a litmus test for a gem stone that's claimed to be a diamond.

What is the purpose of the litmus paper test?
Litmus paper test is done to check the pH value of a solution. pH is a measure of acidity and or alkalinity of a solution.
Why amines give litmus paper test?
to test the acidity or alkalinity of a solution.
Why do you test with litmus paper?
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation
Why is uric acid called a acid?
Because it is an acid. A way to test if a material is an acid or a base is to test it with litmus if the litmus turns red then it is acid if it turn blue it is a base or alkaline. uric acid turn litmus red. making it an acid.
