An excess of `AgNO_3` is added to `100mL` of a `0.01M` solution of dichlorotetraaquachromin (III) chloride. The number of moles of `AgCl` precipitated would be:

Options

A. 0.01
B. 0.001
C. 0.002
D. 0.003

Answer

B

Explanation

The complex will ionise as :
`[Cr(H_(2)O)_(4)Cl_2]Cl` `` `[Cr(H_(2)O)_(4)Cl_(2)]^(+)` + `Cl^(-)`
0.01 M 0.01M 0.01M
(0.001 mol) (0.001 mol) (0.001 mol)
`therefore` No of moles of AgCl precipitated on adding excess of `AgNO_3` solution = 0.001 mol
