Question

Will oxidation number increase or decrease in a reduction reaction? give example​

Answer 1

YOUR answer

Coefficients do not affect oxidation numbers. The oxidized atom increases in oxidation number and the reduced atom decreases in oxidation number. ... The carbon monoxide (CO) is the reducing agent since it contains the element that is oxidized. The Fe3+ ion is the oxidizing agent since it is reduced in the reaction.
