उत्तर
(i) \[\ce{\underset{\text{lead nitrate sol.}}{Pb[NO3]} + \underset{\text{sodium sulphate sol.}}{Na2SO4}->\underset{\text{soluble salt sod. nitrate}}{2NaNO3} + \underset{\text{ppt. lead sulphate}}{PbSO4 v}}\]
(ii) \[\ce{Pb[NO3]2 + \underset{\text{sodium chloride sol.}}{2NaCl}->\underset{\text{sodium nitrate (soluble)}}{2NaNO3} + \underset{\text{lead (II) chloride ppt.}}{PbCl2 v}}\]
