Hydrogen Peroxide

Question

Statement I: The boiling point of H₂O₂ cannot be determined experimentally by distillation.
Statement II: H₂O₂ decomposes into H₂ and O₂ below its boiling point.

Easy

A

Statement I and Statement II are true.
B

Statement I is true and statement II is false.
C

Statement I is false and Statement II is true.
D

Statement I and Statement II are false.

Solution

The boiling point of H₂O₂ cannot be determined experimentally by distillation.
As it undergoes decomposition below its boiling point as H₂Oand O₂ .Due to presence of weak peroxy bond it undergoes decomposition.
H₂O₂ → H₂O+ 1/2O₂
Because of this reason H₂O₂ is purified from its aqueous solution by distillation under reduced pressure
Statement I is true and statement II is false.
