Question

What happens when: (iii) sodium peroxide dissolves in water?

Answer 1

Sodium peroxide dissolves in water

When sodium peroxides $\left({\mathrm{Na}}_2{\mathrm{O}}_2\right)$ are dissolved in water $\left({\mathrm{H}}_2\mathrm{O}\right)$, hydrogen peroxides $\left({\mathrm{H}}_2{\mathrm{O}}_2\right)$, as well as sodium hydroxide $\left(\mathrm{NaOH}\right)$, are generated.

${\mathrm{Na}}_2{\mathrm{O}}_2\left(\mathrm{s}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)\stackrel{}{\to }2\mathrm{NaOH}\left(\mathrm{s}\right)+{\mathrm{H}}_2{\mathrm{O}}_2\left(\mathrm{aq}\right)$

Uses of Sodium Hydroxide

• Generally uses as soap as it is basic in nature.
• It is used as a drain cleaner.
• It is used in the manufacturere of drugs.
