No it does not.
If it is pure water, it doesn't change.
yes a blue litmus paper turns red when put into an acid
Acid turns it in red, while base will turn it blue.
Acids turn blue litmus to red. Bases turn red litmus blue.
Blue!! Because pool water is alkaline and alkalis turn red litmus paper into blue.
Red litmus paper remains red when dipped into an acid. Blue litmus paper will turn red in an acid. Similarly, Blue litmus remains blue in a base. Red litmus turns blue in a base.
If rainwater is dipped into a blue litmus paper, there will likely be no color change. Blue litmus paper turns red in the presence of an acid, but rainwater is typically slightly acidic due to dissolved carbon dioxide, which is not strong enough to turn blue litmus red.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Acids turns Blue litmus to Red. Bases turns Red litmus to Blue.
carbon dioxide turns wet blue litmus red because carbon dioxide dissolves in water to form weak dibasic acid called carbonic acid
Actually, no. Acids turn litmus red, not bases.Bases just turns litmus blue.
Any substance that's pH value over 8.0 turns red litmus to blue.
