turns acidic
Blue litmus paper turns RED in an acid. Red litmus paper turns BLUE in a base.
Nothing - red litmus paper indicates the presence of bases.
Red litmus paper is used for alkaline solutions.
When blue litmus paper touches an acid it becomes red. This is the type of litmus paper that detects acids. When red litmus paper touches an acid, it will remain red. This is used to test a base.
Litmus paper is an indicator that turns red in acidic solutions and blue in basic solutions. The chemical equation for litmus paper reacting with an acid could be: H+ (from the acid) + Litmus paper (Red) -> Litmus paper (Blue). Similarly, the equation for litmus paper reacting with a base could be: OH- (from the base) + Litmus paper (Red) -> Litmus paper (Blue).

Litmus will allow you to tell if a solution is a acid or a base.
litmus paper indicates wether a substance is an acid or a base if it is an acid the paper is turns red, if base it turns blue
Blue litmus paper will turn red when dipped in dilute nitric acid. This color change indicates that the solution is acidic. Nitric acid is a strong acid and will donate protons to the litmus paper, causing the color change.
If liquid detergent turns red litmus paper blue, it is likely a base. Red litmus paper turns blue in the presence of a base, indicating that the detergent is causing a basic reaction.
An acid turns blue litmus paper red. This is because the acid donates a proton (H+) to the water in the litmus paper, changing the pH and causing the litmus paper to change color.
The easiest (most basic) way is to place litmus paper in (or above) the solution. Red Litmus will turn blue in the presence of an acid.
