1.	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)^(2-)` and `MnO_(4)^(-)`C. `MnO_(4)^(-)` and `MnO_(4)^(2-)`D. `Cu^(+)`and `Cu^(2+)`
Answer» Correct Answer - C `MnO_(4)^(-)` is pink while `MnO_(4)^(2-)` is green, ozone oxidizes `MnO_(4)^(2-)` to `MnO_(4)^(-)`
