$K Cl O_{3} + C_{2} O_{4} H_{2} + H_{2} S O_{4} \to K_{2} S O_{4} + C O_{2} + C l_{2} + H_{2} O$

Maximum change in oxidation number $= Cl$

KClO3​+C2​O4​H2​+H2​SO4​→K2​SO4​+CO2​+Cl2​+H2​O Maximum change in oxidation number =Cl

$K Cl O_{3} + C_{2} O_{4} H_{2} + H_{2} S O_{4} \to K_{2} S O_{4} + C O_{2} + C l_{2} + H_{2} O$

Maximum change in oxidation number $= Cl$
