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)?
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! :)
