CHXII09:COORDINATION COMPOUNDS

322218 In solid \(\mathrm{CuSO}_{4} \cdot 5 \mathrm{H}_{2} \mathrm{O}\), copper is coordinated to

1 4 water molecules
2 5 water molecules
3 One sulphate molecule
4 One water molecule
CHXII09:COORDINATION COMPOUNDS

322219 \(\mathrm{FeSO}_{4}\) solution mixed with \(\left(\mathrm{NH}_{4}\right)_{2} \mathrm{SO}_{4}\) solution in 1:1 molar ratio gives the test of \(\mathrm{Fe}^{2+}\) ion but \(\mathrm{CuSO}_{4}\) solution mixed with aqueous ammonia in 1:4 molar ratio does not give the test of \(\mathrm{Cu}^{2+}\) ion. Explain why?

1 \(\mathrm{Cu}^{2+}\) changes to \(\mathrm{Cu}\)
2 \(\mathrm{Cu}^{2+}\) changes to \(\mathrm{Cu}^{+}\)
3 \(\mathrm{Cu}^{2+}\) forms complex and is not ionisable
4 \(\mathrm{Cu}^{2+}\) become immobile in ammonia
