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.

Tap water will not cause any colour change when tested with litmus paper. Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.
Methanol is a neutral substance and typically does not change the color of litmus paper. Litmus paper changes color in the presence of acidic or alkaline substances.
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.
The color of litmus paper turns red when it comes in contact with an acidic solution, and blue when it comes in contact with a basic solution. The color change of litmus paper can help determine the pH level of the substance being tested.
Aluminium oxide does not have any effect on litmus paper. Litmus paper is typically used to test for acidic or basic substances, and since aluminium oxide is a neutral compound, it will not cause any color change in the litmus paper.
Yes, litmus paper can be used to test the acidity of water. When dipped into water, litmus paper will change color to indicate whether the water is acidic (turns red) or basic (turns blue). This color change occurs due to chemical reactions between the water and the litmus paper.
The water solution of iodine turn blue litmus paper to red.

Methanol is a neutral substance and typically does not change the color of litmus paper. Litmus paper changes color in the presence of acidic or alkaline substances.
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.
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.
The color of litmus paper turns red when it comes in contact with an acidic solution, and blue when it comes in contact with a basic solution. The color change of litmus paper can help determine the pH level of the substance being tested.
Aluminium oxide does not have any effect on litmus paper. Litmus paper is typically used to test for acidic or basic substances, and since aluminium oxide is a neutral compound, it will not cause any color change in the litmus paper.
Yes, litmus paper can be used to test the acidity of water. When dipped into water, litmus paper will change color to indicate whether the water is acidic (turns red) or basic (turns blue). This color change occurs due to chemical reactions between the water and the litmus paper.
Blue litmus paper would be used and if the chemical is an acid the litmus paper would turn red.
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation
Alcohol does not significantly affect litmus paper. Litmus paper is primarily used to test for acidity or alkalinity in solutions by changing color, and alcohol does not typically cause a noticeable color change on litmus paper.
When ammonia gas is produced at the bottom of the test tube and comes in contact with the litmus paper at the mouth of the test tube, it reacts with the water on the litmus paper to form ammonium hydroxide. This reaction changes the color of the litmus paper from red to blue, indicating the presence of ammonia gas. The ammonia gas diffuses up the test tube to reach the litmus paper due to differences in concentration.
