How you get HCl acid?

Answer 1

As we all know, HCl is highly reactive acid therefore it is not recommended to dilute it by simply adding water to it. By adding water to HCl, exothermic reaction will takes place and it may cause damage to the experimenter.

In order to dilute HCl, pour HCl in water as water is good absorber of heat and will absorb heat from the exothermic reaction thereby acting safely towards the experimenter.

Answer 2

Hydrogen chloride gas can be formed by adding concentrated sulfuric acid to sodium chloride:

2NaCl(s) + H2SO4(l) → Na2SO4(s) + 2HCl(g)

This gas can be used in reactions directly, or be bubbled through water to form the aqueous acid. In water, HCl readily ionises into H+ and Cl+, thus decreasing the pH of the system.

Answer 3

Hydrochloric acid (HCl) is commonly produced by mixing hydrogen gas with chlorine gas under controlled conditions. This reaction forms hydrogen chloride gas, which can then be dissolved in water to create hydrochloric acid. Industrial production of HCl typically follows this method to ensure proper safety measures are in place.
