Common mistake
Misunderstanding Oxidation
Students often confuse oxidation with the loss of electrons instead of recognizing it as an increase in oxidation state.
To clarify, remember that oxidation is defined as an increase in oxidation state. For example, in the reaction of magnesium with oxygen, magnesium goes from an oxidation state of 0 to +2, indicating oxidation. Always check the oxidation states before concluding.
