Water is oxidised to oxygen by

Options

(a) KMnO₄
(b) O₃
(c) H₂O₂
(d) F₂

Correct Answer:

F₂

Explanation:

When fluorine reacts with water:

2F_2(g)     +    2H₂O_(I)    →     4H⁺_(aq)  +  4F^–_(aq)   +  O_2(g)

In the above reaction, water is oxidized to oxygen and fluorine is reduced to fluoride ion. Water is oxidised from -2 oxidation state to zero oxidation state. this increase in the oxidation state means oxidation of water.
