Convert :
(a) Two soluble metallic nitrates to insoluble metallic chlorides using dil. HCl.
(b) Hydrochloric acid to nascent chlorine.
(a)
(i). AgCl is insoluble solid where as AgNO3 is soluble.
AgNO3 (aq)+HCl (aq)→AgCl (solid)+HNO3 (aq)
(ii). PbCl2 is insoluble solid where as Pb(NO3)2 is soluble.
Pb(NO3)2(aq)+ 2 HCl→PbCl2 (solid)+2 HNO3 (aq)
(b) Hydrochloric acid reacts with Nitric acid to produce nascent chlorine.
3 HCl (aq) + HNO3 (aq)→ NOCl + 2H2O (l) +2 [Cl]Nascent Chlorine
