Write chemical reactions to justify that hydrogen peroxide can function as an oxidising as well as reducing agent. |
|
Answer» Hydrogen peroxide, `H_(2)O_(2)` acts as an oxdizing as well as reducing agent in both basic and alkaline media. Reaction involving oxidizing actions are: (1) `2Fe^(2+)+2H^(+)+H_(2)O_(2) to 2Fe^(3+)+2H_(2)O` (2) `Mn^(2+)+H_(2)O_(2) to Mn^(2+)+2OH^(-)` (3) `PbS+4H_(2)O_(2) to PbSO_(4)+4H_(2)O` (4) `2Fe^(+)+H_(2)O_(2) to 2Fe^(3+)+2OH^(-)` Reactions involving reduction actions are: `2MnO_(4)^(-)+6H^(+)+5H_(2)O_(2) to 2Mn^(2+)+8H_(2)O+5O_(2)` (2) `I_(2)+H_(2)O_(2)+2OH to 2l+2H_(2)O+O_(3)` `HOCl+H_(2)O to H_(2)O^(+)+Cl+O_(2)` `2MnO_(3)+3H_(2)O to 2MnO_(2)+3O_(2)+2H_(2)P+2OH` |
