Answer
Methods for concentrating hydrogen peroxide and obtaining this compound in anhydrous form, based on removal or binding of water from the surface of solution in an open vessel or in a closed volume and also on binding of water directly in a $H _2 O _2$ solution, are described.
Differences between structures of $H _2 O _2$ and $H _2 O ^{-}$
In gaseous phase, water molecule $\left( H _2 O \right)$ has a bent form with a bond angle of $104.5^{\circ}$. The $O - H$ bond length is 95.7 pm . The structure of $H _2 O$ can be shown as:
Hydrogen peroxide has a non-planar structure both in gas and solid phase. The dihedral angle in gas and solid phase is $111.5^\circ$ and $90.2^\circ$ respectively. The structure of $H_2O_2$ can be shown as:
Uses- Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/ cold sores, gingivitis). This product works by releasing oxygen when it is applied to the affected area. The release of oxygen causes foaming, which helps to remove dead skin and clean the area.
