$\mathrm{X}_2$ reacts with water to form $\mathrm{HX}(\mathrm{aq})$ and $\mathrm{HOX}(\mathrm{aq}) . \mathrm{Y}_2$ reacts with water to form $\mathrm{O}_2(\mathrm{~g})$, $\mathrm{Y}^{-}(\mathrm{aq})$ and $\mathrm{H}^{+}(\mathrm{aq}) \cdot \mathrm{Z}_2$ does not react with water. $\mathrm{X}_2, \mathrm{Y}_2, \mathrm{Z}_2$ are respectively
