  • The oxidation and reduction reactions mediated by hydrogen peroxide  <img alt="\left(\mathrm{H}_2 \mathrm{O}_2\right)" src="https://entrancecorner.oncodecogs.com/gif.latex?%5Cleft%28%5Cma

The oxidation and reduction reactions mediated by hydrogen peroxide  \left(\mathrm{H}_2 \mathrm{O}_2\right) in an acidic medium are externally slow, whereas they are rapid in an alkaline medium. What is the reason behind this observation?

 

Option: 1

\mathrm{H}_2 \mathrm{O}_2  is more stable in an acidic medium.

 


Option: 2

 The concentration of  \mathrm{H}_2 \mathrm{O}_2 is higher in an alkaline medium.


Option: 3

\mathrm{H}_2 \mathrm{O}_2 acts as a catalyst in an alkaline medium.


Option: 4

The reaction rate is affected by the pH of the medium.

The pH of the medium influences the rate of oxidation and reduction reactions involving hydrogen peroxide. In an acidic medium, the reaction rate is slower, meaning it proceeds at a slower pace. On the other hand, in an alkaline medium, the reaction rate is faster. This difference in reaction rate is due to the impact of pH on the reaction mechanism and the availability of reactive species. Therefore, the pH of the medium plays a crucial role in determining the rate of oxidation and reduction reactions mediated by \mathrm{H}_2 \mathrm{O}_2
