Question

Distinguish by using HCl. 

Lead nitrate solution and silver nitrate solution.

Answer 1

	Lead nitrate solution	Silver nitrate solution
1.	On adding dilute HCl, a white precipitate of lead chloride (PbCl2) is formed.	On adding dilute HCl, a curdy white precipitate of silver chloride (AgCl) is formed.
2.	The precipitate dissolves on heating.	The precipitate does not dissolve on heating.
3.	\[\ce{Pb(NO3)2 + 2HCl -> PbCl2 + 2HNO3}\]	\[\ce{AgNO3 + HCl -> AgCl + HNO3}\]
