Ammonia is a base, and will turn red litmus blue.
Litmus will turn blue in ammonia due to its alkaline/basic nature.
Color of litmus will change.Red litmus will change into blue.
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
Green
Hydrochloric acid is an acidic solution, so when litmus powder is added to it, the litmus powder would most likely turn red. This is because litmus paper turns red in acidic solutions and blue in basic solutions.
red
Red litmus paper does not change color when it rains; it remains red. Litmus paper is used to test pH levels, and rainwater is typically neutral to slightly acidic, which does not affect the color of red litmus paper. The color change occurs when red litmus paper is exposed to a basic (alkaline) solution, turning blue.
Dry ammonia is neutral to litmus because it does not produce any protons (H+) or hydroxide ions (OH-) when dissolved in water. Litmus paper changes color in the presence of these ions, so if a substance does not produce them when dissolved, it will not affect the color of litmus paper.
water is a neutral sullusion it goes green.
Litmus turns red when exposed to an acidic solution. Litmus is red in acid and blue in alkali.
Red, and an alikili goes blue.
