what simple test would you use to identify the possible presence of HCl(aq)? What result do you expect if the solution is HCl(aq)?

Answer 1

Hi Lili,
I'll try this one. You could add silver carbonate to the solution. A white precipitate is produced, while a colorless, odorless, gas is evolved which produces a white precipitate in limewater (calcium hydroxide).

Hope I helped! :)
