If excess of `AgNO_(3)` solution is added to 100mL of a 0.024 M solution of dichlorobis (ethylenediamine) cobalt (III) chloride . How many mole of AgCl be precipitated ?

A

`0.0012`

B

`0.0016`

C

`0.0024`

D

`0.0048`

Text Solution

Verified by Experts

The correct Answer is:
C
`Co^(3+) + 2 Cl^(-) + 2 (en)`
net charge = +1
Thus , complex is
`[Co(en)_(2) Cl_(2)]^(+) Cl^(-) to [Co(en)_(2) Cl_(2)]^(+) + Cl^(-)`
Only one `Cl^(-)` which is precipitated as AgCl
100 mL of 0.024 M complex = 2.4 millimol = 0.0024 mol
