What is true for hydrogen peroxide and ozone ?

Options

A. `H_(2)O_(2)` acts as a stronger reducing agent in alkline medium than in acidic medium
B. `H_(2)O_(2)` and `O_(3)` both are oxiducing agents as well as bleaching agent
C. `H_(2)O_(2)` forms a hyrate, `H_(2)O_(2).H_(2)O`
D. Ozone is used in the manufacutre of potassium permangnate from pyrolusite.

Answer

ABCD

Explanation

(A) In alkaline solution, its reducing character is more than in acidic medium.
`H_(2)O_(2) to O_(2)+2H^(+)2e^(-)` " , " `2OH^(-)+H_(2)O_(2) to O_(2) +2H_(2)O+2e^(-)`
(B) Correct statements.
(C ) Due to H-bonding it forms a hydrate `H_(2)O_(2).H_(2)O` ("melting point 221 K")`.
`(D) K_(2)MnO_(4)+O_(3)+H_(2)O to KMnO_(4)+2KOH+O_(2)`
