The compound `Yba_2Cu_3O_7` which shows super conductivity has copper in oxidation state_____. Assume that the rare earth element yttrium is in its usual `+3` oxidation state.

A

`3//7`

B

`7//3`

C

3

D

7

Text Solution

Verified by Experts

The correct Answer is:
B
`Yba_(2) overset(**)(C)u_(3) O_(7)`
`3 + 2 xx 2 + 3x - (2xx 7) = 0`
`3 + 4 + 3x - 14 = 0`
`3x = 7`
`x = (7)/(3)`
