Question

differentiate between Dilute hydrochloric acid and dilute sulphuric acid by using silver nitrate solution

Answer 1

Actually on adding lead nitrate to HCl, PbCl2 precipitates out and on heatingthe solution it redissolves. ... On adding more of dilute hydrochloric acid, the precipitate will dissolve in it. Lead Nitrate forms a white precipitate in dilute sulphuric acid and does not dissolve in excess of it.
