Because to exchange protons (from Litmus to ammonia) some water molecules are needed for transfer:
LitH+(red) + H2O + NH3 --> [ Lit + H3O+ + NH3 ] --> Lit(blue) + H2O + NH4+(aq)
Litmus paper will turn red in the presence of HCl, indicating acidity. However, it will not show any significant color change when added to methyl benzene, as it is a nonpolar solvent and does not react with litmus paper to cause a color change.
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
Ammonia gas can be tested in these ways:1. It has a pungent smell2. It turns MOIST red litmus paper blue3. Test its alkalinity in water (pH ~ 11)4. It will extinguish a lighted splint5. It will easily dissolve in water
The red litmus paper will remain red in acetic acid. Acetic acid is a weak acid and does not change the color of red litmus paper.
When neutral litmus solution is added to an alkaline solution, the litmus solution will turn blue. This change in color indicates that the solution is basic or alkaline in nature. Litmus paper is commonly used as an indicator to determine the acidity or alkalinity of a solution.

When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
When ammonia is added to mustard, a color change would typically result in a yellow or orange-yellow color becoming more intense or bright. This is due to the alkaline nature of ammonia enhancing the yellow pigment present in mustard.

When litmus is added to a solution of borax, the litmus paper may turn blue due to the alkaline nature of borax. Borax is a weak base that can cause litmus paper to change its color from red to blue.
the same color red
The red litmus paper will remain red in acetic acid. Acetic acid is a weak acid and does not change the color of red litmus paper.
When neutral litmus solution is added to an alkaline solution, the litmus solution will turn blue. This change in color indicates that the solution is basic or alkaline in nature. Litmus paper is commonly used as an indicator to determine the acidity or alkalinity of a solution.
Litmus dye cannot float as it is a soluble substance that dissolves in water. When added to a liquid, litmus dye will evenly disperse in the solution and change color based on the pH of the solution.
When a base is added to red litmus paper, the indicator turns blue. This is because red litmus paper is used to indicate acidic conditions, so a base would cause the paper to change color to blue.
litmus paper nutral
It appears to be red if a lot of hydrogen ions is removed by a higher concentration of base added
