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.
HCl + H 2 O → [H 3 O] + + Cl −. The resulting solution is called hydrochloric acid and is a strong acid. The acid dissociation or ionization constant, K a, is large, which means HCl dissociates or ionizes practically completely in water. Even in the absence of water, hydrogen chloride can still act as an acid.

In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...
POCl 3 reacts with water to give hydrogen chloride and phosphoric acid: O=PCl 3 + 3 H 2 O → O=P(OH) 3 + 3 HCl. Intermediates in the conversion have been isolated, including pyrophosphoryl chloride, O(−P(=O)Cl 2) 2. [9] Upon treatment with excess alcohols and phenols, POCl 3 gives phosphate esters: O=PCl 3 + 3 ROH → O=P(OR) 3 + 3 HCl
