What is the gram equivalent weight of hydrogen peroxide as reductant?

The gram equivalent weight of hydrogen peroxide (H₂O₂) as a reductant can be calculated based on its ability to donate electrons in a chemical reaction.

Understanding Equivalent Weight

Equivalent weight is defined as the mass of a substance that can react with or replace one mole of hydrogen atoms in a reaction. For hydrogen peroxide, this depends on the specific reaction it undergoes.

Calculation of Equivalent Weight

The molecular weight of hydrogen peroxide is approximately 34 grams per mole. When it acts as a reductant, it can donate two electrons. Therefore, the gram equivalent weight can be calculated using the formula:

• Gram Equivalent Weight = Molecular Weight / n

Here, "n" represents the number of electrons transferred. For hydrogen peroxide, n is 2.

Final Calculation

Using the formula:

• Molecular Weight of H₂O₂ = 34 g/mol
• n = 2
• Gram Equivalent Weight = 34 g/mol / 2 = 17 g/equiv

Thus, the gram equivalent weight of hydrogen peroxide as a reductant is 17 grams per equivalent.
