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.
As soap is alkaline in nature, it turns red litmus paper blue
Litmus paper usually turns either blue or pink (sometimes red) which indicates whether the chemical is an acid or a base. If the paper turns blue it is a base. If pink or red it is an acid.
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
yellow
Ammonia is a base, and will turn red litmus blue.
Color of litmus will change.Red litmus will change into blue.
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.
Litmus will turn blue in ammonia due to its alkaline/basic nature.
