Acid will turn litmus paper red.
I believe, that acid makes blue litmus paper turn red.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
Acid: Red litmus
Acids turn litmus paper red. Bases turn litmus paper blue. If the paper turns orange, its an acid.
Acids turn blue litmus to red. Bases turn red litmus 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.
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.
When an acid touches Litmus paper it turns red (pink).
In an acid solution the blue litmus paper become red.
Yes - with blue litmus paper if the solution was an acid it would turn red. if the solution was an alkali it would stay blue or if the solution is neutral it would turn green:)
Litmus paper will turn blue when detecting a base, and red when detecting an acid.
They turn it either red or blue. Acids turn blue litmus paper red and bases turn red litmus paper blue.
