Which of the following statements is`//`are correct?
In the reaction `xCu_(3)P+yCr_(2)O_(7)^(2-)rarrCu^(2+)+H_(3)PO_(4)+Cr^(3+)`

Options

A. `Cu` in `Cu_(3)P` is oxidised to `Cu^(2+)` whereas `P` in `Cu_(3)P` is also oxidised to `PO_(4)^(3-)`.
B. `Cu` in `Cu_(3)P` is oxidised to `Cu^(2+)` whereas `P` in `Cu_(3)P` is reduced to `H_(3)PO_(4)`.
C. In the conversion of `Cu_(3)P` to `Cu^(2+)` and `H_(3)PO_(4),11 "electrons" are involved.
D. The value of `x` is `6`

Answer

A, C, D

Explanation

`4H_(2)O+overset(+1xx3-3)(Cu_(3)p)rarr3cu^(2+)+H_(3)PO_(4)+11e^(-)+5H^(o+)]xx6`
`6e^-)+14H^(o+)+Cr_(2)O_(7)^(2-)rarr2Cr^(3+)+7H_(2)O]xx11`
`ulbar(6Cu_(3)P+124H^(o+)+11Cr_(2)O_(7)^(2-)rarr18Cu^(2+)+6H_(3)PO_(4)+22Cr^(3+)+53H_(2)O)`
