    I'm guessing chlorine is +5. Since the overall charge of any molecule is 0 and the oxidation of O is -2*3= -6 and Na can be only +1 that leaves chlorine to be +5 to make the overall charge 0. I gots the feeling i might be wrong though.

    OP:
    oxygen is always -2 (most of the time)
    Na is always +1

    its +5, 3x(-2)=-6, bring it over the 0 then equals +6, all group 1 metals, in this case Na, are +1, bring that over the 0 then becomes -1, (+6)+(-1)=+5
