Just wanna make sure, if i did it correct or not.

Question

Cl2 + 2NaBr --> Br2 + 2NaCl
(0)---(+1)--(-1)---(0)------(+1)(-1)

So Cl2 loss = oxidation
Br2 Gain = Reduction

Am I correct ? Thanks

Answer 1

I don't know what your definition is of oxidation/reduction. Your answeres ae not right.
My definition is that oxidation is the loss of electrons and reductin is the gain of electrons.
You have the oxidation states marked correctly. So Cl goes from 0 on the left to -1 on the right. That is a gain of electrons which makes it reduced (and it is the oxidizing agent).

Answer 2

Cl2----->2NaCl=reduction
2NaBr---->Br2=oxidation
