How many electrons are transferred in the reaction of hydrogen peroxide with iron (II) ion in
acidic solution to form iron (III) ion and water?
To determine the number of electrons transferred in the reaction between hydrogen peroxide (H2O2) and iron (II) ion (Fe2+) in acidic solution to form iron (III) ion (Fe3+) and water (H2O), we need to examine the oxidation states of the elements involved.
In this reaction, hydrogen peroxide acts as an oxidizing agent, causing the iron (II) ion to be oxidized to iron (III) ion. The oxidation state of iron changes from +2 to +3.
The general rule is that the change in oxidation state corresponds to the number of electrons transferred. In this case, since the oxidation state of iron increases by 1, it means that one electron is transferred per iron atom.
Therefore, the number of electrons transferred in the reaction between hydrogen peroxide and iron (II) ion is 1 electron.
