The paper changes colour from red to blue. This is because when you mix MgO with water, you now have Mg(OH)2 solution which is basic and hence changes the colour of red litmus paper to blue.
Acid can't turn red litmus paperbur base canturn it blue .
When litmus paper touches an acid, the paper changes to red. When it touches a base, the paper changes to blue. By comparing the color the litmus paper changed to by a chart, you could determine how strong or weak that acid or base is.
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.

Blue litmus paper turns RED in an acid. Red litmus paper turns BLUE in a base.
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.

When litmus paper touches an acid, the paper changes to red. When it touches a base, the paper changes to blue. By comparing the color the litmus paper changed to by a chart, you could determine how strong or weak that acid or base is.
Litmus paper usually turns either blue or pink (sometimes red) which indicates whether the chemical is an acid or a base. If the paper turns blue it is a base. If pink or red it is an acid.
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 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 turns RED in an acid. Red litmus paper turns BLUE in a base.

Nothing, red litmus paper changes in the presence of an acid not a base, blue litmus paper turns red with nitric acid
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).
an acid
yes a blue litmus paper turns red when put into an acid
