In part because of its high polarity, HCl is very soluble in water (and in other polar solvents). Upon contact, H 2 O and HCl combine to form hydronium cations [H 3 O] + and chloride anions Cl − through a reversible chemical reaction: HCl + H 2 O → [H 3 O] + + Cl −. The resulting solution is called hydrochloric acid and is a strong acid.
Physical properties of hydrochloric acid, such as boiling and melting points, density, and pH, depend on the concentration or molarity of HCl in the aqueous solution. They range from those of water at very low concentrations approaching 0% HCl to values for fuming hydrochloric acid at over 40% HCl.

1 part of aqueous HCl (hydrochloric acid, 37% by weight) 1 part of aqueous H 2 O 2 (hydrogen peroxide, 30%) at 75 or 80 °C, typically for 10 minutes. This treatment effectively removes the remaining traces of metallic (ionic) contaminants, some of which were introduced in the SC-1 cleaning step. [1]
Baumé degrees (light) was calibrated with 0 °Bé (light) being the density of 10% NaCl in water by mass and 10 °Bé (light) set to the density of water. Consider, at near room temperature: +100 °Bé (specific gravity, 3.325) would be among the densest fluids known (except some liquid metals), such as diiodomethane .

The formaldehyde content generally ranges from 5–37% and the methanol content may range from 9–56%. In the United States alone, about 20 million liters (roughly 5.3 million gallons) of embalming fluid are used every year.
