Write the reactions of $F_{2}$ and $C l_{2}$ with water?

Open in App

Solution

(i) Fluorine reacts with water to produce oxygen and ozone.

$2 F_{2} (g) + 2 H_{2} O (l) ⟶ 4 H F (a q) + O_{2} (g) 3 F_{2} (g) + 3 H_{2} O (l) ⟶ 6 H F (a q) + O_{3} (g)$

(ii) Chlorine reacts with water to some extent to give a green solution.

$C l_{2} + H_{2} O S u n l i g h t ⟶ H C l + H O C l$

The Hypochlorous Acid, HClO, is not very stable and the solution readily decomcomposes, especially when exposed to sunlight, yielding HCl and Oxygen.

$2 H O C l ⟶ 2 H C l + O_{2}$ .
