`H_(2)O_(20` is manufactured these days

A

By the action of `H_(2)O_(2) ` on `BaO_(2)`

B

By the action of `H_(2)SO_(4)` on `Na_(2)O_(2)`

C

By electrolysis of `50% H_(2)SO_(4)`

D

By burning hydrogen in excess of oxygen

Text Solution

Verified by Experts

The correct Answer is:
c
Electrolysis of `50%` sulphuric acid gives per disulphuric acid `(H_(2)S_(2)O_(8))` which on distillation yields `30%` solution of hydrogen peroxide.

H_(2)O_(20 is always stored in black bottles because

A person inhales 640g of O_(20 per day. If all the O_(2) is used for converting sugar into CO_(2) and H_(2)O , how much sucrose (C_(12)H_(22)O_(11)) is consumed in the body in one day and what is the heat evolved ? (DeltaH_("combination of sucrose ")=-5645kJ mol^(-1))

The strength of H_(2)O_(2) is expressed in several ways like molarity, normality,% (w/V), volume strength, etc. The strength of "10 V" means 1 volume of H_(2)O_(2) on decomposition gives 10 volumes of oxygen at 1 atm and 273 K or 1 litre of H_(2)O_(2) gives 10 litre of O_(2) at 1 atm and 273 K The decomposition of H_(2)O_(2) is shown as under : H_(2)O_(2)(aq) to H_(2)O(l)+(1)/(2)O_(2)(g) H_(2)O_(2) can acts as oxidising as well as reducing agent. As oxidizing agent H_(2)O_(2) is converted into H_(2)O and as reducing agent H_(2)O_(2) is converted into O_(2) . For both cases its n-factor is 2. :. "Normality " "of" H_(2)O_(2) "solution" =2xx "molarity of" H_(2)O_(2) solution 20mL of H_(2)O_(2) solution is reacted with 80 mL of 0.05 MKMnO_(4) "in acidic medium then what is the volume strength of" H_(2)O_(2) ?
