either colorless or a color between red and blue
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.
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.
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.
Technically the litmus paper should stay blue, but depending on where you live and how your water is treated it can become pink or red. If you use distilled water then it will stay a neutral color but with traces of minerals and chlorine to make tap water safer to drink, the water either becomes slightly acidic or basic. It really just depends on where you live.
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.
When red litmus paper is dipped in distilled water, it will remain red, indicating that the water is neutral and does not change the acidity. Similarly, when blue litmus paper is dipped in the same distilled water, it will also remain blue. This observation confirms that distilled water has a neutral pH of around 7, which does not affect the litmus papers' color.
Red litmus paper would remain red because distilled water is essentially neutral, meaning it has a pH pf 7. Red litmus paper does not measure pH and only changes to a blue color when placed in acidic solutions, anything from pH 6.9-0.
The colour remain unchanged.
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.
THE COLOUR of the litmus paper will not change as a salt solution is neutral
