A green coloured solution of a salt changes its colour to light pink on passing ozone through it. Which of the following species represent pink and green colour respectively.A. `Mn^(2+)` and `MnO_2`B. `MnO_4^(Ө)` and `MnO_4^(2-)`C. `Co^(2+)` and `Co^(3+)`D. `MnO_4^(2-)` and `MnO_4^(Ө)` |

Answer» Correct Answer - D `[MnO_(4)^(2-) rarr MnO_(4)^(Ө) + e^(Ө)] xx 2` `O_(3) 2 H^(oplus) + 2 e^(Ө) rarr O_(2) + H_(2) O` `ulbar(underset(("Green")) (2MnO_(4)^(Ө)) + O_(3) + 2 H_(oplus) rarr underset(("Pink"))(2MnO_(4)^(Ө)+ O_(2) + H_(2) O))`. |
