उत्तर १
Sulphuric acid precipitates the insoluble sulphate from lead nitrate solution.
\[\ce{Pb(NO3)2 + H2SO4 -> PbSO4 + 2HNO3}\]
Lead nitrate reacts with hydrochloric acid to give a white ppt. of lead chloride.
\[\ce{Pb(NO3)2 + 2HCl -> PbCl2 + 2HNO3}\]
उत्तर २
Bring a glass rod dipped in ammonia solution near the mouth of each test tube containing dil. HCl and dil. H2SO4 each.
The dil. HCl gives white fumes of ammonium chloride.
The dil. H2SO4 has no such fumes.
