Molecular Structure

 H Cl

Production and Reactions
Hydrogen chloride can be obtained by the action of sulfate acid to the sodium chloride salt.

2NaCl H2SO4 ---> Na2SO2 HCl

Sulfur dioxide and oxygen mixtures can be obtained by the effect of sodium chloride.

SO2 1/2 O2 H2O NaCl ---> Na2SO4 2HCl

Hydrochloric acid can release hydrogen as a typical acid property by acting on many metals such as zinc, iron, magnesium or aluminum.
2HCl Mg ---> MgCl H2
2HCl Fe ---> FeCl H2
When mixed in a certain ratio with nitric acid, a liquid called king water can be obtained.
They can be dissolved in a mixture of water (hydrochloric acid - nitric acid) which can affect most metals.
When silver nitrate reacts with hydrochloric acid, they may form a white chloride silver precipitate.
