Water is oxidised to oxygen by
Options
(a) KMnO₄
(b) O₃
(c) H₂O₂
(d) F₂
Correct Answer:
F₂
Explanation:
When fluorine reacts with water:
2F2(g) + 2H2O(I) → 4H+(aq) + 4F–(aq) + O2(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.
