Question

For the chlorate ion clo3 what are the oxidation states of the cl and o respectively

Answer 1

Answer: Oxidation state of chlorine is +5 and oxidation state of oxygen is -2.

Explanation: Oxygen is more electronegative than chlorine so it will be in negative oxidation state, as ion given is not the peroxide so the oxidation state of oxygen will be -2.

In chlorate ion, there is one chlorine atom surrounded by three oxygen atoms having (- 2) oxidation state each.

In ${ClO_3}^{-}$ ion,

Oxidation state of oxygen= -2

Oxidation state of Cl = x

Net charge = -1

Net charge = Summation of oxidation states of each atoms constituting the ion.

$x+(3\times (-2))=-1$

$x=+5$

Answer 2

Answer: Oxidation state of chlorine is +5 and oxidation state of oxygen is -2.

Explanation: Oxygen is more electronegative than chlorine so it will be in negative oxidation state, as ion given is not the peroxide so the oxidation state of oxygen will be -2.

In chlorate ion, there is one chlorine atom surrounded by three oxygen atoms having (- 2) oxidation state each.

In  ion,

Oxidation state of oxygen= -2

Oxidation state of Cl = x

Net charge = -1

Net charge = Summation of oxidation states of each atoms constituting the ion.
