a litmus tells us if a substance is acidic or alkaline
an acid will turn red litmus paper blue and an alkali will turn blue litmus paper red.
if an unknown substance is tested with litmus and the colour did not change, then the substance is said to be neutral or it can be simply water.
note that water is needed for acids to show its acidic properties........
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 paper can be used to determine if a solution is acidic or basic
Acid turns blue litmus red and maintains red litmus at the same color.
The litmus paper remain unchanged in a neutral solution.
The indicators in litmus are extracted from lichens; the color of litmus depends on the pH of the solution.
no
Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.
You probably mean litmus paper. (see https://en.wikipedia.org/wiki/Litmus.)

Color of litmus will change.Red litmus will change into blue.
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 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.
Online science class does not mean you can just google for answers. Read your textbook!
Acids turn blue litmus to red. Bases turn red litmus blue.
The colour is red in acidic solutions.
litmus paper turns blue litmus red when tested on an acid and red litmus blue when tested on a base
