consider the reaction shown below and determine whether it is a redox reaction or not. If it is, state which element is being oxidized and which element is being reduced.

Question

Answer 1

A reaction is defined as a redox reaction if the oxidation states of the elements change.

In this reaction, Fe⁰ → Fe²⁺ (in FeCl₂), so Fe is oxidized

Also, H⁺ (in HCl) → H⁰ (in H₂) so H is reduced
