Question

Give the reaction when sodium peroxide dissolved in water.

Answer 1

The reaction of Sodium peroxide in water:

1. Sodium peroxide reacts with distilled water to produce Sodium hydroxide$\left(\mathrm{NaOH}\right)$ and Hydrogen peroxide$\left({\mathrm{H}}_2{\mathrm{O}}_2\right)$.
2. Because of the presence of $\mathrm{NaOH}$ the solution will be strongly alkaline.
3. $\underset{\mathrm{Sodium}\mathrm{peroxide}}{{\mathrm{Na}}_2{\mathrm{O}}_2\left(\mathrm{aq}\right)}+\underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\mathrm{Sodium}\mathrm{hydroxide}}{2\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}\mathrm{peroxide}}{{\mathrm{H}}_2{\mathrm{O}}_2\left(\mathrm{l}\right)}$
