Question

Complete the following reactions
(i) `O_(2)^(2-)+H_(2)O rarr` (ii) `O_(2)^(-) +H_(2)O rarr`

Answer 1

`O_(2)^(2-)` represents a peroxide ion
`O_(2)^(-)` represents a superoxide ion
(i) Peroxide ion react with water to form `H_(2)O_(2)`
`O_(2)^(2-)+2H_(2)O rarr 2OH^(-)+underset("Hydrogen peroxide")(H_(2)O_(2))`
(ii) Superoxide ion react with water to form `H_(2)O_(2)` and `O_(2)`
`2O_(2)^(-)+2H_(2)O rarr 2OH^(-) + underset("Hydrogen peroxide")(H_(2)O_(2))+ O_(2)`
