Chlorine, the yellowish-green gas with sufocating odour is evolved when the solid sodium chloride mixed with manganese dioxide, is heated with concentrated

H_{2} S O_{4}

.

N a Cl + H_{2} S O_{4} ⟶ N a H S O_{4} + H Cl

M n O_{2} + 4 H Cl ⟶ M n C l_{2} + 2 H_{2} O + C l_{2}

Q. $M n O_{2}$ and $H_{2} S O_{4}$ are added to $N a Cl$ . The greenish yellow gas liberated is

$C l_{2}$

$N H_{3}$

$N_{3}$

$H_{2}$

Chlorine, the yellowish-green gas with sufocating odour is evolved when the solid sodium chloride mixed with manganese dioxide, is heated with concentrated $H_{2} S O_{4}$ .
$N a Cl + H_{2} S O_{4} ⟶ N a H S O_{4} + H Cl$
$M n O_{2} + 4 H Cl ⟶ M n C l_{2} + 2 H_{2} O + C l_{2}$
