Answer 1

Answer:

blue litmus to red as they are acidic......

Answer 2

Answer 1

Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F).

Answer 2

Chlorine reacts with HCl in the moist litmus paper to form hydrochloric acid.However, chlorine is a powerful bleach and it bleaches the litmus paper, making it colourless.

Answer 3

red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Under acidic conditions, the solution is red, and under alkaline conditions, the solution is blue.

Answer 3

The combination of indicators gives the paper the ability to determine an approximate pH of acids or bases. In the presence of a strong acidic solution, the pH paper will turn red, and if a strong alkaline or basic solution is applied, it will turn violet. Neutral solutions turn green.
