Which of the following is correct regarding the reaction of fluorine with water? 2 ~F ₂(g)+2 H ₂ O (l) 4 H ⁺(a q)+4 ~F ⁻(a q)+ O ₂(g)
Options
- AFluorine is oxidized to F ⁻
- BWater is oxidized to O ₂
- CWater is reduced to H ⁺
- DOxidation state of fluorine does not change
Correct answer
B. Water is oxidized to O ₂
Step-by-step solution
Increase in oxidation state is oxidation. Here, oxidation state of oxygen atom changes from -2 to 0 . Hence, water is oxidised to O ₂ .
