Alchemists of the Middle Ages recognized that hydrochloric acid (then known as spirit of salt or acidum salis) released vaporous hydrogen chloride, which was called marine acid air. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar. Molecular weight calculation: 1.00794 + 35.453 ›› Percent composition by element Report the uncertainty as half of the difference between the two mass measurements (ex. Products. Historical uses of hydrogen chloride in the 20th century include hydrochlorinations of alkynes in producing the chlorinated monomers chloroprene and vinyl chloride, which are subsequently polymerized to make polychloroprene (Neoprene) and polyvinyl chloride (PVC), respectively. 1.00794+35.453. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. Molarity of HCl solution = 9.86M . Later, the Hargreaves process was developed, which is similar to the Leblanc process except sulfur dioxide, water, and air are used instead of sulfuric acid in a reaction which is exothermic overall.
