When blue litmus paper is placed in soapy water, it remains blue because soap is typically alkaline (basic). Litmus paper is used to test pH levels, and blue litmus paper indicates a neutral or basic environment. If the water were acidic, the blue paper would turn red, but in this case, the soapy water keeps it blue.

Why is the pH of soap 9?
The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.
What happens to red litmus paper when it is placed in hot water?
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.
What happens to red litmus paper if dipped in water?
Red litmus paper remains red when dipped in water. Litmus paper is used to test for acidity or basicity, and red litmus paper turns blue in basic solutions. If the water being tested is neither acidic nor basic, the red litmus paper will not change color.
What color of litmus is water?
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.
When strips of blue and pink litmus paper are put in water the paper changes?
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.

How does an acid affect blue litmus paper?
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.

What will happen if litmus paper is diped in lime water?
The litmus paper will turn blue if dipped in lime water, indicating that the lime water is basic. Lime water is a solution of calcium hydroxide, which is a strong base that can turn litmus paper blue.
What is the reaction with litmus paper after boiling the water and ferric chloride mixture?
Boiling the water and ferric chloride mixture will not change the color of litmus paper, as litmus paper is not sensitive to the presence of ferric chloride. Litmus paper is typically used to test for acidity or basicity in a solution.
What does not change litmus paper color?
water
