A non-stoichiometric compound `Cu_(1.8)S` is formed due to incorporation of `Cu^(2+)` ions in the lattice of cuprous sulphide. What percentage of `Cu^(2+)` ions the total copper centent is present in the compound

A

88.88

B

11.11

C

99.8

D

89.8

Text Solution

Verified by Experts

The correct Answer is:
B
`Cu^(+2)=x, Cu^(+1)=1.8-x, x xx(+2)+(1.8-x)=+2,x=0.2`
`1.8rarr0.2,100rarr ? , 11:11`
