Question

What substance is reduced in the reaction 2Fe 2+ + CI2 = 2Fe 3+ + 2CI- ?

Answer 1

`$Cl_(2)$` is reduced in the reaction

Step-by-step explanation:

The given reaction is

`$2Fe^(2+)+Cl_(2) \to 2Fe^(3+)+2Cl^(-)$`

The oxidation number of
`$Fe$` is changed from
`$+2\, \to \, +3$`

`$Fe^(2+) \to Fe^(3+)+e^(-)$`

And The oxidation number of
`$Cl$` is changed from
`$0\, \to \, -1$`

`$Cl_(2)^(0) + 2e^(-) \to 2Cl^(-)$`

Hence,
`$Fe^(2+)$` is oxidized and
`$Cl_(2)$` is reduced
