In the reaction Al + FeCl3 → Fe + AlCl3 which substance is oxidized?

OpenStudy (joannablackwelder):

Reactants oxidation numbers: Al: 0, Fe: 3, Cl:-1. Products oxidation numbers: Al:1, Fe: 0, Cl:-1. The oxidized substance is the one that lost electrons. Can you tell me which one that is? Note: electrons are negative.

OpenStudy (anonymous):

Fe

OpenStudy (joannablackwelder):

No, when the oxidation number goes down, that means it gained electrons.
