Litmus paper turns green when it is exposed to a substance that is close to neutral on the pH scale, typically around pH 7. This change indicates that the solution is neither acidic (which turns litmus paper red) nor basic (which turns litmus paper blue).
Red litmus paper will turn blue in the presence of a base. Toothpaste is a base, so the litmus paper would turn blue.
No, a base turns blue litmus paper red. Litmus paper is red in acidic solutions and blue in basic solutions.
TRUE!!!! Litmus will turn BLUE in alkali. However, Litmus paper is a rather unsophisicated methof testing for acids/alkalis. Universal Indicatort will give a range of colours Red, orange, yellow, green , blue, purple indigo. for strong acid (red) through neutral (green) , to strong alkali (Indigo). It is more sensative to acid /alkali strength.
Acid turns it in red, while base will turn it blue.
Acid will turn litmus paper red.
It would turn Green
It turns green
dark green
If the antacid is basic, litmus paper would turn blue. If the antacid is acidic, litmus paper would turn red.

Acids turn blue litmus to red. Bases turn red litmus blue.

No, red litmus paper turns blue in a basic solution and remains red in neutral or acidic solutions. It only changes to green if it is exposed to a very strong base.

HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
