The effects of red and blue litmus when dipped in solutions of acid base and neutral are to show their overall pH. This is caused through a chemical reaction between the solution and a coating on the strips.

Acids turn litmus red. Litmus paper is a pH indicator that changes color in response to the acidity or alkalinity of a solution. In acidic conditions, litmus paper will turn red, while in alkaline conditions, it will turn blue.
Actually, some acids do burn litmus paper. Hydrochloric acid, for example, can burn paper, but the litmus on litmus paper shields the paper from the acid. Sulfuric acid, however, has dehydration properties, and would suck the water right out from the paper, charring it instantly.
Color of litmus will change.Red litmus will change into blue.
Red litmus paper remains red when dipped in water. Litmus paper is used to test for acidity or basicity, and red litmus paper turns blue in basic solutions. If the water being tested is neither acidic nor basic, the red litmus paper will not change color.
Litmus paper is a threshold-specific acid-base test. ___________________________________________________________________ it is a test used to find the pH level of certain materials. it will turn blue if the object is basic and red if it is acidic.
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
Litmus turns red when exposed to an acidic solution. Litmus is red in acid and blue in alkali.
An indicator, for example Litmus.
Litmus is a natural dye indicator extracted from lichens.They react with acid (blue litmus turns red)& bases(red litmus turns blue) .Paper made with litmus dye indicators are called litmus paper and used in chemical laboratories.
Acids turn blue litmus to red. Bases turn red litmus blue.
