Question

At room temperature, the reaction between water and fluorine produces

• A. $HF$ and $H_2O_2$
• B. $HF, O_2$ and $F_2O_2$
• C. $F^{-}, O_2$ and $H^{+}$
• D. $HOF$ and $HF$

Answer 1

Answer: (C)

At room temperature, the reaction between water and fluorine produces $F ^{-}, O _{2}$ and $H ^{+}$.

Fluorine, being non-polar molecule, readily dissolves with water and forms mixture of oxygen and ozone as shown below

$2 F _{2}+2 H _{2} O \longrightarrow 4 HF + O _{2} $

$3 F _{2}+3 H _{2} O \longrightarrow 6 HF + O _{3}$

$HF$ exist as $H ^{+}$ and $F ^{-}$ in a solution.
