fe3+ is reduced to fe2+ by using
Updated On: Aug 9, 2023
H2O2 in the presence of NaOH
Na2O2 in water
H2O2 in the presence of H2SO4
Na2O2 in the presence of H2SO4
Hide Solution
Verified By Collegedunia
The Correct Option is C, D
Solution and Explanation
The correct answer is/are option/s (C)&(D) :
H2O2 in the presence of H2SO4
Na2O2 in the presence of H2SO4
By using H₂O₂ in the presence of NaOH. In this H₂O₂ will act as a reducing agent and OH ion will act as a base. The balanced reaction is as follows:
2 Fe³⁺ + 2 H₂O₂ + 2 OH⁻ → 2 Fe²⁺ + 2H₂O + O₂
Another way is by using, Na₂O₂ in water. In the reaction, sodium peroxide will act as a strong oxidizing agent and therefore donate the oxygen atom. Water will provide the medium. The reaction for the same is as follows:
2Fe³⁺ + Na₂O₂ + 2H₂O → 2 Fe²⁺ + 2NaOH + H₂O₂
