(i) Chlorine gas is prepared by heating manganese dioxide with Cone. HCl
`MnO_(2)+4HClrarrMnCl_(2)+2H_(2)O+Cl_(2)`
(ii) Chlorine gas is prepared when mixture of NaCl and `MnO_(2)` is treated with Cone. `H_(2)SO_(4)`
`4NaCl+MnO_(2)+4H_(2)SO_(4)rarr4NHSO_(4)+MnCl_(2)+2H_(2)O+Cl_(2)`
(iii) Chlorine gas is prepared by treating Cone . HCl on `KMnO_(4)`
