(b) Red litmus paper is introduced into a solution of ammonia in water

(c) Red litmus paper is introduced in Caustic soda solution?

Answers:

(a) The Blue litmus paper will turn into red as the solution is acidic.

(b) There will be no change in the colour.

(c) The Red litmus paper will turn into blue as the solution is basic.
