Litmus paper is typically blue. If water is tested with blue litmus paper and it turns red, it indicates that the water is acidic. However, if there is no color change, the water is neutral.
The water solution of iodine turn blue litmus paper to red.
The blue litmus paper turns red in acidic solutions, and the pink litmus paper turns blue in basic solutions. This color change is due to a change in the pH of the water affecting the chemical structure of the litmus dye on the paper.
If it is pure water, it doesn't change.
dark green
Red litmus paper will stay red when placed in hot water, as it only changes color in the presence of acids. If the hot water is acidic, then the red litmus paper will turn blue.
water
Litmus paper is sensitive to changes in acidity or alkalinity, not simply the presence of water. Water is neutral and does not significantly alter the pH of a solution, so it does not cause a noticeable change in the color of litmus paper.

blue
The water solution of iodine turn blue litmus paper to red.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. Some types of Litmus paper will not change color in pure water (such as the 1-12 pH yellow litmus paper), others will turn a purple color as an indication of the solution being not an acid (red) or a base (blue).
The blue litmus paper turns red in acidic solutions, and the pink litmus paper turns blue in basic solutions. This color change is due to a change in the pH of the water affecting the chemical structure of the litmus dye on the paper.
either colorless or a color between red and blue
baking powder will not show any colour change in litmus soltion because water is absent but wen it is mixed wid water and then subjected to the litmus solution, the red litmus wud change to blue.
If it is pure water, it doesn't change.
In acid solution, blue colour of litmus is changed into red. In basic sol litmus change to blue.
