# NaClO3 was used as a weedkiller. Give the oxidation state of chlorine in NaClO3. watch

1. need help!!, anyone awake?
2. 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.

This would be correct.

that is bloody right m8. well done

OP:
oxygen is always -2 (most of the time)
Na is always +1
then just do a bit of maths and there u go

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
6. +5 is it?
