Dissolved in concentrated hydrochloric acid

1. Hydrogen chloride is a colorless gas with a pungent odor. Pure hydrochloric acid is a colorless liquid that fogs in the air (due to its high volatility) and has a pungent acidic smell. Crude hydrochloric acid is yellow due to the presence of the impurity ferric chloride. Commercially available concentrated hydrochloric acid has a concentration of 20.24% and a density of 1.097 grams per cubic centimeter; it is an azeotropic mixture. 2. It is soluble in water; at 0°C, about 500 volumes of hydrogen chloride can be dissolved in 1 volume of water. An aqueous solution of hydrogen chloride is acidic and is called hydrochloric acid; it is commonly referred to as hydrochloric acid. It is mainly used in the production of dyes, fragrances, medicines, various chlorides, and corrosion inhibitors. 3. Hydrogen chloride is a colorless, toxic gas with a pungent odor at normal temperature and pressure. 4. Hydrochloric acid is an aqueous solution of hydrogen chloride, and it is a colorless or slightly yellow liquid. It does not burn in air, is thermally stable, and does not decompose until around 1500°C. 5. Pure hydrochloric acid is a colorless liquid that forms mist in the air (due to its high volatility) and has a pungent acidic odor. Crude hydrochloric acid is yellow due to the presence of the impurity ferric chloride. 6. Concentrated hydrochloric acid can no longer dissolve hydrogen chloride once it reaches a certain concentration, as concentrated hydrochloric acid is typically 35%-37% in concentration, has a density of 1.097 g/cm3, and is an azeotropic mixture.

After concentrated hydrochloric acid reaches a \"certain concentration,\" it can no longer dissolve hydrogen chloride. Is there an accurate value for this \"certain concentration\"?

I wonder if the concentrated hydrochloric acid mentioned by the original poster has reached saturation

Does concentrated hydrochloric acid generate heat when it dissolves HCL? ? I don’t feel like it’s being generated. . Even if it does occur, it’s probably minimal. . . . If the temperature is above minus 17 degrees, it will definitely dissolve

Concentrated hydrochloric acid can dissolve more hydrogen chloride when it is unsaturated. Concentrated hydrochloric acid is generally 35%-37%.

It is necessary to consider the operating temperature and pressure during the dissolution process; by looking up the vapor pressure of concentrated hydrochloric acid at those temperatures, it is possible to determine whether further dissolution is possible

I have been in contact with an HCL gas absorption tower that uses dilute hydrochloric acid (10%) to absorb HCL gas, resulting in 30% concentrated hydrochloric acid. The absorption process releases a large amount of heat, but no intermediate cooling is required

After reaching saturation, it will no longer dissolve; of course, heat is released during the dissolution process

It is exothermic; when using HCl falling-film absorption, cooling water is also required

Excuse me, folks upstairs – how is the heat of dilution for concentrated hydrochloric acid calculated? 30% hydrochloric acid needs to be diluted
