Hydrochloric acid was first discovered around 800 AD by the alchemist Jabir ibn Hayyan
One way to test a gas to identify it as an HCL gas is to dip a glass rod in ammonia and place it in the gas. If a white smoke is produced, the gas is HCL gas.
HCl gas is not an acid because it does not produce H+ ions in solution when dissolved in water. However, when HCl gas dissolves in water to form hydrochloric acid (HCl aqueous), it dissociates into H+ and Cl- ions, making it acidic.
Hydrochloric acid (HCl) is a colorless solution. It does not have a distinct color.
When acetone bisulfite reacts with HCl, sulfur dioxide gas is evolved.
The chemical formula for hydrogen chloride gas, also known as hydrochloric acid gas, is HCl.

When NH4Cl is heated, it decomposes into NH3 gas and HCl gas. The balanced chemical equation for this reaction is: NH4Cl(s) -> NH3(g) + HCl(g).
The chemical formula for hydrogen chloride gas, also known as hydrochloric acid gas, is HCl.
Hydrogen gas
Yes, fluorite does react with hydrochloric acid (HCl) to produce hydrogen fluoride gas. This reaction can be observed by effervescence and the formation of a gas when fluorite is exposed to HCl.
Dry HCl, or anhydrous hydrogen chloride, exists in the gas phase at room temperature and pressure. It only becomes a liquid when compressed or cooled to very low temperatures.
HCl gas is molecular HCl in the gaseous phase, HCl acid is HCl in solution with water, and can be said to be in the form H+ Cl-. (Or to be a pendant, H3O+ Cl- as techincally protons do not exist on their own in solution.) It is this dissociation of the molecule into constituent ions which gives an acid its properties. On a physical level, HCl gas is a yellow/green gas, and HCl acid is a clear solution.
You can determine the moles of HCl formed by using a balanced chemical equation for the reaction between hydrogen gas and chlorine. Calculate the stoichiometric ratio of hydrogen to HCl in the balanced equation to determine the moles of HCl formed from the given moles of hydrogen gas.
