Vedclass · Answer

(C) The balanced chemical reaction is: $2KClO_3 + 3H_2C_2O_4 + H_2SO_4 \rightarrow K_2SO_4 + 2KCl + 6CO_2 + 4H_2O$ Calculation of oxidation states: $1$. For $Cl$ in $KClO_3$,the oxidation state changes from $+5$ to $-1$ in $KCl$. The change is $|-1 - 5| = 6$. $2$. For $C$ in $H_2C_2O_4$,the oxidation state changes from $+3$ to $+4$ in $CO_2$. The change is $|4 - 3| = 1$. $3$. The oxidation states of $S$,$H$,$K$,and $O$ remain unchanged in this reaction. Thus,$Cl$ undergoes the maximum change in oxidation number.

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