Vedclass · Answer

(D) $1$. $MnO_2$ reacts with conc. $HCl$ to form $MnCl_2$,$Cl_2$ gas,and $H_2O$. It does not form $Mn^{4+}$ ions because $Mn^{4+}$ is unstable in the presence of $Cl^-$ ions. This statement is correct.$2$. $MnO_2$ reacts with hot conc. $H_2SO_4$ to produce $MnSO_4$,$O_2$ gas,and $H_2O$. This statement is correct.$3$. When $MnO_2$ is fused with $KOH$ in the presence of an oxidizing agent like air,$KNO_3$,$PbO_2$,or $NaBiO_3$,it forms green potassium manganate $(K_2MnO_4)$. This statement is correct.$4$. The decomposition of $KMnO_4$ is indeed catalyzed by light (sunlight). Therefore,the statement that it is 'not catalysed by sunlight' is incorrect.
