Write the equation for its laboratory preparing of hydrogen chloride gas mentioning the condition required.

Open in App

Solution

The equations are:
$N a C l + H_{2} S O_{4} < 200^{\circ} C \to N a H S O_{4} + H C l_{(g)}$
$2 N a C l + H_{2} S O_{4} > 200^{\circ} C \to N a_{2} S O_{4} + 2 H C l_{(g)}$
