Answer 2

Answer:

For instance, ammonia gas, which is alkaline, turns red litmus paper blue. Chemical reactions other than acid–base can also cause a color change to litmus paper. For instance, chlorine gas turns blue litmus paper white – the litmus dye is bleached, because of presence of hypochlorite ions.
