red
When red litmus paper is dipped in ammonia, it turns blue. Ammonia is a basic (alkaline) substance, and the change in color indicates the presence of a base. This reaction happens because the ammonia raises the pH of the solution, causing the red litmus paper to change color.
As soap is alkaline in nature, it turns red litmus paper blue
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
When a sugar solution is dipped in red litmus paper, there is no change in the color of the paper. This is because sugar is a neutral substance and does not affect the pH of the solution. Red litmus paper remains red in neutral or acidic solutions, indicating that the sugar solution does not have acidic properties.
When white litmus paper is dipped in potassium permanganate, it does not change color, as potassium permanganate is a neutral solution and does not affect the acidity or basicity of the litmus paper. White litmus paper is designed to indicate pH changes, turning red in acidic conditions and blue in basic conditions. Since potassium permanganate itself is not acidic or basic, the litmus paper remains unchanged.

blue
Depends on the litmus paper. Red litmus will not turn but blue litmus will turn redish pink.

Red!

Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
Blue litmus paper turns pink when dipped into a base. This is because the color change indicates a shift in pH level from acidic to basic.
Blue litmus paper remains blue when dipped in milk of magnesia because milk of magnesia is basic in nature.
When red litmus paper is dipped in grapefruit juice, it typically remains red. This is because grapefruit juice is slightly acidic, and red litmus paper does not change color in acidic conditions. If the juice were alkaline, the paper would turn blue, but grapefruit juice does not have that property.
When a sugar solution is dipped in red litmus paper, there is no change in the color of the paper. This is because sugar is a neutral substance and does not affect the pH of the solution. Red litmus paper remains red in neutral or acidic solutions, indicating that the sugar solution does not have acidic properties.
It turns blue. Since chalk ( CaCo3) is a base and when pink litmus paper reacts with a base it turns blue
