What is hydrogen peroxide?
Peroxide is a compound that contains an oxygen-oxygen single bond
Hydrogen peroxide (H 2 O 2 ) is a colorless liquid at room temperature which is slightly viscous than water, with a bitter taste.
Hydrogen peroxide is non-linear, non-planar molecule that has an open book-like structure.
The -Oxygen-Oxygen- linkage is called peroxy linkage.
The repulsion between two lone-pairs results in a high barrier for rotation of hydrogen peroxide molecule
Hydrogen peroxide was first isolated in the year 1818 by Louis Jacques Thénard by reacting barium peroxide with nitric acid.
Hydrogen peroxide is an unstable compound and it readily decomposes into oxygen and water,
therefore it acts as a good oxidizing agent and is generally stored in weakly acidic solution
Preparation of Hydrogen Peroxide
i) The reaction of Barium peroxide with acids gives us hydrogen peroxide
ii) The reaction of Sodium Peroxide with acid also gives us hydrogen peroxide
iii) Oxidation of isopropyl alcohol also results in the formation of hydrogen peroxide
iv) By electrolysis of an aqueous solution of sulfuric acid or acidic ammonium bisulfate followed by hydrolysis of the per-oxy-disulfate which is formed at the anode
v) From 2-alkyl anthraquinone
This is the most important manufacturing process to get a high yield of hydrogen peroxide
This reaction involves the oxidation of 2-alkyl anthraquinone in presence of oxygen to produce hydrogen peroxide and the original anthraquinone compound
