Answer: Oxidation state of chlorine in the given compound is +7.
Explanation:
Oxidation state is defined as the number which is assigned to the element when it gains or loose electrons. If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state.
We take the oxidation state of chlorine atom be 'x'.
Oxidation state of sodium atom = +1
Oxidation state of oxygen atom = -2
Evaluating the oxidation state of chlorine atom:
[tex]+1+x+4(-2)=0\\\\x=+7[/tex]
Hence, the oxidation state of chlorine in the given compound is +7.
