Describe the Large scale manufacture of hydrochloric acid.

Describe the Large scale manufacture of hydrochloric acid.

Answers

Raw materials:
- Hydrogen obtained as a byproduct of petroleum industry; electrolysis of brine or from water by Bosch process;
- Chlorine obtained from the electrolysis of brine or as fused calcium chloride.

Procedure:
- A small sample of hydrogen gas is allowed through a jet and burnt in excess chlorine gas.


Precaution: A mixture of equal volumes of hydrogen and chlorine explodes when put in sunlight.

- The hydrogen chloride gas formed is dissolved in water over glass beads.
- The glass beads increase the surface area over which absorption takes place.
- Commercial hydrochloric acid is about 35% pure.
- Hydrochloric acid is transported in steel tanks lined inside with rubber.
- If the acid comes into contact with exposed parts of metal or with rust, it forms iron (III) chloride that makes the acid appear yellow.
