Red color in acidic solutions and blue color in basic solutions.
Red litmus paper indicates the presence of an acid when it remains red, as acids do not change its color. If the paper turns blue, it indicates a basic (alkaline) solution. Therefore, red litmus paper is used specifically to test for acidity.
Could be all that ammonia in the filtrate. Ammonia is a weak base.
A Blue litmus paper turns red in acid and stays blue in alkalin A red litmus paper turns blue in alkaline and stays red in acid
Acidic substances turn blue litmus red
A base turn the color of the paper in blue.
Litmus paper is a type of paper used to test the acidity or alkalinity of a substance. It changes color in response to pH changes, turning red in acidic conditions and blue in alkaline conditions. Litmus paper is commonly used in science experiments and in various industries to quickly determine the pH level of a solution.

If a substance changes the color of a blue litmus paper to red, it is acidic blue to red
Acid: Red litmus
acid turn litmus into red.Base turn litmus into blue
Blue litmus paper turns RED in an acid. Red litmus paper turns BLUE in a base.
Nothing, red litmus paper changes in the presence of an acid not a base, blue litmus paper turns red with nitric acid
