Question

2
Give the equation for preparation of HCl gas by synthesis. State two conditions involved in the synthesis.
​

Answer 1

Answer:

Direct synthesis

2 NaCl + 2 H2O → Cl2+ 2 NaOH + H. The pure chlorine gas can be combined with hydrogen to produce hydrogen chloride in the presence of UV light: Cl2(g) + H2(g) → 2 HCl(g) As the reaction is exothermic, the installation is called an HCl oven or HCl burner

Answer 2

Answer:

The reaction is :

H2 + Cl2 --------> 2 HCl [g]

The conditions are:

1. Sunlight
2. Jet of hydrogen
