1.	Which of the following statement (s) is /are not true about the following decomposition reaction. 2KClO_3 rarr 2KCl+3O_2
Answer» Potassium is undergoing oxidation Chlorine is undergoing oxidation Oxygen is reduced None of species are undergoing oxidation or reduction SOLUTION :`overset(+1+5+2)(2KClO_3)rarroverset(+1-1)(2KCl)+3overset(0)(O_2)` (a) Since O.N. of potassium does not change , it neither undergoes oxidation nor reduction. (B) O.N. of Cl decreases from +5 `(KClO_3)` to -1 (in KCl), THEREFORE , it is undergoing reduction. (c) O.N. of O increases from -2 (in `KClO_3` ) to zero (in `O_2`) therefore , O is oxidised . (d) This statement is not correct because Cl is undergoing reduction and O is undergoing oxidation.
