What is the spin only magnetic moment when HCI is added to an aqueous solution of `CoCl_(2) ` . Its colours changes from reddish pink to deep blue . Colour .

A

3.88BM

B

5.9 BM

C

7 BM

D

35BM

Text Solution

Verified by Experts

The correct Answer is:
B
Number of unpaired electrons in Fe =5
ltagnetic moment , `mu = sqrt(n(n+2))=srt(5(5+2))
`=sqrt(32)= 5.9 BM `
