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+)`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` |
