Which of the following staement (s) `is//are` not true about the following decomposition reaction
`2KCIO_(3)rarr2KCI+3O_(2)`

Options

A. Potassium is undergoing oxidation
B. Chlorine is undergoing oxidation
C. Oxygen is reduced
D. None of the species are undergoing oxidation or reduction

Explanation

writing the O.N each element above its symbol we have
`2KCIO_(3)rarr 2DCI+3O_(32)`
(a) since O.N of k does not change therefore K neither undergoes reduction nor oxidation thus option (a) is not corret
(b) since O.N of CI decreases form +5 in `KCIO_(3)` to -1 in KCI therefore CI undergoes reductio i.e option (b) isnot correct
(c ) O.N of O increses form -2 in `KIO_(3)` ot 0 in `O_(2)` therefore O is oxidised i.e option (c ) not correct ltbRgt (d) This statement is not correct because CI undergoing reduction and O is undergoing oxidation Thus all option are incorrect
