A solution of hydrogen peroxide, \(\text{H}_2\text{O}_2\), is titrated with potassium permanganate, \(\text{KMnO}_4\), according to the following equation:
\[5\text{H}_2\text{O}_2 + 2\text{KMnO}_4 + 3\text{H}_2\text{SO}_4 \rightarrow 5\text{O}_2 + 2\text{MnSO}_4 + 8\text{H}_2\text{O} + \text{K}_2\text{SO}_4\]
It requires 46.0 mL of 0.145 Mol/L \(\text{KMnO}_4\) to titrate 50.0 mL of the solution of \(\text{H}_2\text{O}_2\).
What is the mole per liter concentration of \(\text{H}_2\text{O}_2\) in the solution?
Answer (2)
The concentration of** hydrogen peroxide** in the solution is 0.3335 M. ;
The concentration of hydrogen peroxide (H₂O₂) in the solution is calculated to be 0.3335 M. This is derived from the moles of KMnO₄ used in titration and the stoichiometry of the balanced chemical equation. By finding the moles of KMnO₄ from its volume and concentration, and relating it to H₂O₂ via the reaction ratios, the concentration is determined.
