It depends. Litmus paper is used to test pH levels. Blue litmus paper turns red in the presence of acids, and red litmus paper turns blue in the presence of alkalines. Litmus paper is purple in neutral conditions.
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.
A base/alkali substance will turn litmus paper blue.
It turns from blue to red or red to blue.ANS2:Acetone will not change the colour of litmus. It is not an ionic substance so it will not produce a change in pH.
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
It's purple the colour can change slightly. isn't that just great purple it's my favourite colour ya know
No an acid will only change the litmus paper red regardless of of the substance color.

Acid; Meaning it is ranked less than seven and at least zero on the pH scale.
A base/alkali substance will turn litmus paper blue.
It is because the red litmus paper only changes its color (from red to blue) when exposed to any basic substance. Hydrochloric acid is acidic, thus there is no change in the color of the red litmus paper, although the acid would change the color of the blue litmus paper (pH paper that tests for acidity; changes from blue to red in the presence of acid)
litmus paper is genrally used to verify whether a substance is acid or base
It turns from blue to red or red to blue.ANS2:Acetone will not change the colour of litmus. It is not an ionic substance so it will not produce a change in pH.
An acidic solution will change blue litmus paper to red and basic solutions change red litmus paper to blue
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........
pH paper and litmus paper
Yellow litmus paper is used to test for the presence of a base in a solution. When the yellow litmus paper turns blue, it indicates the solution is basic. This simple test helps to determine the pH of a substance quickly and easily.
Litmus paper is used to indicate whether a substance is acidic or basic. Blue litmus paper turns red in the presence of an acid, while red litmus paper turns blue in the presence of a base.
