2.15 understand these displacement reactions as redox reactions.

When a more reactive halogen displaces a less reactive one this is a redox reaction.
This means that one element has been reduced (gained electrons) and one has been oxidised (lost electrons.)
Helpful hint!
Oilrig helps to remind you how redox reactions go:

Oxidation
Is
Loss
Reduction
Is
Gain

      It is a gain of electrons, which means loss of charge as electrons are negatively charged.

    Yeah, there's a point where tradition becomes confusing

    I think it means that reduction has gained electrons and oxidations has lost electrons

    I think it's also because there is a loss of oxygen at the same time? Or am I barking up the wrong tree?!?!

    oxidisation is a gain in electrons whereas reduction is a loss in electrons
