Which of the following statement is incorrect

$\begin{array}{1 1}(a)\;H_2O_2\;\text{is an oxidising agent }\\(b)\;H_2O_2\text{is an reducing agent}\\(c)\;H_2O_2\;\text{has acidic properties}\\(d)\;H_2O_2\;\text{has basic properties}\end{array}$

1 Answer

$H_2O_2\; \text{has basic properties}$
Hydrogen peroxide is a week acid. In an aqueous solutions it ionizes forming hydronium-ion and peroxid-ion:
$H_2O_2 + H_2O ⇄ H_3O^{+} + {O_2}^{2–}$.
Hence (d) is the correct answer.
