HNO₃+HCl = NOCl+ 2H₂O + 2[Cl]
Nascent chlorine reacts with metals like Ag, Au, Pt. to give their respective chlorides.
Au +3[Cl] = AuCl₃
Pt +4[Cl] = PtCl₄
Ag +[Cl] = AgCl( This reaction is possible only to some extent because formation a protective layer of insoluble Silver Chloride with stops the rection to proceed.)
