Test for the nitrate ion - indicates nitric acid - and the sulphate ion - indicates sulphuric acid.
to a dilute solution of nitic acid add piece of aluminium foil followed by sodium hydroxide and heat. Test for ammonia - smell (smells of smelling salts) and action on litmus, turns litmus blue.
to a dilute solution of sulphuric acid, add barium chloride follwed by dilute hydrochloric acid. A white ppt indicates sulphate ion present and hence sulphuric acid.
