    Reaction with Alkali
    • Fluorine on reaction with cold or hot alkali releases gases differently.
      \mathrm{2F_{2}\: +\: 2NaOH\: \rightarrow \: 2NaF\: +\: OF_{2}\: +\: H_{2}O}
                   (cold dilute)

      \mathrm{2F_{2}\: +\: 4NaOH\: \rightarrow \: 4NaF\: +\: O_{2}\: +\: 2H_{2}O}
                (hot concentrated)
    • Other halogens form hypohalite with dilute NaOH and halate with conc. NaOH.
      \mathrm{X_{2}(g)\: +\: 2OH^{-}\: \overset{150^{o}C}{\longrightarrow} \: X^{-}\: +\: OX^{-}\: +\: H_{2}O}
                                                         (Hypohalite ion)

      \mathrm{X_{2}(g)\: +\: 6OH^{-}\: \overset{70^{o}C}{\longrightarrow} \: 5X^{-}\: +\: XO^{-}_{3}\: +\: 3H_{2}O}
                                                             (Halate ion)
