Analysis shows that nickel oxide has formula `Ni_(0.98)O_(1.00),` the `%` of `Ni^(3+)` is `x%`. Then 'x' is 

Text Solution

Verified by Experts

The correct Answer is:
4
`N_(0.98)^(i)O_(1.00)(or)N_(98)^(i)O_(100),Ni^(+3)=(98-x)`
`x(+3)+(98-x)(+2)-200=0 , x+196-200=0 therefore x=4`
`"for 98 gm of Ni"rarr4Ni^(+3)," for 10 grams atom "rarr?(100xx4)/(98)=4.08`
