Question

Why is $HCl$ not used to make the medium acidic in oxidation reactions of $KMn{O}_4$ in an acidic medium?

• A. Both $HCl$ and $KMn{O}_4$ act as oxidising agents
• B. $KMn{O}_4$ oxidises $HCl$ into $C{l}_2$ which is alsoan oxidising agent
• C. $KMn{O}_4$ is a weaker oxidising agent than $HCl$
• D. $KMn{O}_4$acts as a reducing agent in the presence of $HCl$

Answer 1

The correct option is B $KMn{O}_4$ oxidises $HCl$ into $C{l}_2$ which is alsoan oxidising agent

$KMn{O}_4+16HCl⟶2KCl+2Mn{Cl}_2+8H_{2}O+5C{l}_2$,Since $KMn{O}_4$ oxidizes $HCl$ into $C{l}_2$,

$HCl$ is not used to make medium acidic.
