Which of the following is incorrect ?

Options

A. `H_(2)O_(2)` is a weak acid
B. `H_(2)O_(2)` is a weak alkali
C. `H_(2)O_(2)` acts as an oxidising agent
D. `H_(2)O_(2)` is a reducing agent

Answer

A

Explanation

`H_(2)O_(2)` is slightly stronger acid than water, if forms series of salt.
`H_(2)O_(2)iffH^(+)+HO_(2)^(-)" "("hydroperoxide ion")`
`H_(2)O_(2)iff2H^(+)+O_(2)^(2-)" "("peroxide ion")`
`H_(2)O_(2)` behaves as oxidising as well as reducing agent in acidic and basic medium.
