What will you observe if Hydrogen chloride gas is passed through blue litmus solution?
What would you observe when :
(a) blue litmus is introduced into a solution of hydrogen chloride gas,
(b) red litmus paper is introduced into a solution of ammonia in water,
(c) red litmus paper is introduced in caustic soda solution?
You enter a laboratory and you are asked to pass a gas through blue litmus solution. How will you be able to tell whether the gas passed in the experiment is hydrogen chloride or ammonia?
