1 \({\text{Pb}}{\left( {{\text{N}}{{\text{O}}_{\text{3}}}} \right)_{{\text{2}}({\text{aq}})}} + {\text{2Na}}{{\text{I}}_{({\text{aq}})}} \to {\text{Pb}}{{\text{I}}_{{\text{2}}({\text{s}})}} + 2{\text{NaN}}{{\text{O}}_{\text{3}}}_{{\text{(aq)}}}\)
2 \({\rm{2N}}{{\rm{a}}_{{\rm{(s)}}}} + 2{{\rm{H}}_{\rm{2}}}{{\rm{O}}_{{\rm{(l)}}}} \to {\rm{2NaO}}{{\rm{H}}_{{\rm{(aq)}}}} + {{\rm{H}}_{{\rm{2(g)}}}}\)
3 \({\rm{AgN}}{{\rm{O}}_{{\rm{3(aq)}}}} + {\rm{HC}}{{\rm{l}}_{{\rm{(aq)}}}} \to {\rm{AgC}}{{\rm{l}}_{{\rm{(s)}}}} + {\rm{HN}}{{\rm{O}}_{{\rm{3(aq)}}}}\)
4 \({\rm{KN}}{{\rm{O}}_{{\rm{3(aq)}}}} + {\rm{NaC}}{{\rm{l}}_{{\rm{(aq)}}}} \to {\rm{KC}}{{\rm{l}}_{{\rm{(aq)}}}} + {\rm{NaN}}{{\rm{O}}_{{\rm{3(aq)}}}}\)
Explanation:
All the species are in aqueous phase
