1.	In KCl because it is ionic compound we assign oxidation no 1+ &1- for K& Cl respectively. but for chlorate ion (ClO3)−1 should we assign -1 for Cl and 0 for Oxygen by following sum rule or should we assign -2 for O and following sum rule +5 for Cl so net oxidation no is -1.which of these is correct ? How ?
