Question

,
20. If excess of AgNO, is added to 100
ml.of a 0.024 M solution of dichlorobis
(ethylene diamine) cobalt (III) chloride
how many moles of AgCl be precipitated?
1) 0.0012
2) 0.0016
3) 0.0024
4) 0.0​

Answer 1

[CoCl2(en)2]Cl. One mole complex contain, one mole of ionisation Cl-.

One mole of complex = one mole of Cl-

∴ One mole of AgCl= One mole of complex=

100×0.024

1000

3) = 0.0024
