COORDINATION COMPOUNDS

28773 \(CuS{O_4}\) reacts with \(KCN\)  solution and forms:

1 \({K_3}[Cu{(CN)_4}]\)
2 \(Cu(CN)\)
3 \(Cu{(CN)_2}\)
4 \({K_4}[Cu{(CN)_6}]\)
COORDINATION COMPOUNDS

28774 A co-ordination complex compound of cobalt has the molecular formulae containing five ammonia molecules, one nitro group and two chlorine atoms for one cobalt atom. One mole of this compound produces three mole ions in an aqueous solution on reacting with excess of \(AgN{O_3},\) \(AgCl\) precipitate. The ionic formula for this complex would be:

1 \([Co{(N{H_3})_5}(N{O_2})]C{l_2}\)
2 \([Co{(N{H_3})_5}Cl][Cl(N{O_2})]\)
3 \([Co{(N{H_3})_4}(N{o_2})Cl]\,[(N{H_3})Cl]\)
4 \([Co{(N{H_3})_5}][{(N{O_2})_2}C{l_2}]\)
COORDINATION COMPOUNDS

28775 In any ferric salt, on adding potassium ferrocyanide, a prussian blue colour is obtained, which is

1 \({K_3}Fe{(CN)_6}\)
2 \(KFe\left[ {Fe{{\left( {CN} \right)}_6}} \right]\)
3 \(FeS{O_4}.Fe{(CN)_6}\)
4 \(F{e_4}{\left[ {Fe{{(CN)}_6}} \right]_3}\)
COORDINATION COMPOUNDS

28776 Prussian blue is formed when

1 Ferrous sulphate reacts with \(FeC{l_3}\)
2 Ferric sulphate reacts with \({K_4}\left[ {Fe{{(CN)}_6}} \right]\)
3 Ferrous ammonium sulphate reacts with \(FeC{l_3}\)
4 Ammonium sulphate reacts with \(FeC{l_3}\)
