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.

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 .
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]
Ammonia solutions decrease in density as the concentration of dissolved ammonia increases. At 15.6 °C (60.1 °F), the density of a saturated solution is 0.88 g/ml; it contains 35.6% ammonia by mass, 308 grams of ammonia per litre of solution, and has a molarity of approximately 18 mol /L.
Experimental measurements of its density give values between 11.5 and 11.66 g/cm 3: ... The hydroxides are dissolved at 80 °C in 37% hydrochloric acid. Filtration of ...
Clorox brand bleach. Bleach is the generic name for any chemical product that is used industrially or domestically to remove color from (i.e. to whiten) fabric or fiber (in a process called bleaching) or to disinfect after cleaning.
