A mixture of potassium chlorate, oxalic acid and sulphuric acid is heated. During the reaction which element undergoes maximum change in the oxidation number?

A

S

B

H

C

Cl

D

C

Text Solution

Verified by Experts

The correct Answer is:
C
`K overset(+5)CIO_3,+ H_2C_2O_4 +H_2 overset(+6)(S)O_4 rarr K_2 overset(+6)(S)O_4 +K overset(-1)(C)I + CO_2 +H_2O` i.e. maximum change in oxidation number is observed and in Cl ( +5 to-1).
