- adj. Pertaining to, or derived from, chlorine having a valence lower than in chlorous compounds.
from The Century Dictionary and Cyclopedia
- In chem., applied to an acid (HCIO) having marked bleaching properties, obtained in solution by distilling bleaching-powder with dilute nitric acid. It is the active principle of bleaching-powder.
Sorry, no etymologies found.
I thus set up an independent program to investigate chemical and spectroscopic properties of compounds of atmospheric importance, focusing on those that are unstable and difficult to handle in the laboratory, such as hypochlorous acid, chlorine nitrite, chlorine nitrate, peroxynitric acid, etc.
Talking about "ion-hungry" water that kills through osmosis makes it sound like it's some sort of ultrapure stuff, but their water has plenty of ions in it, since the electrolysis that produces it makes hypochlorous acid, hydrochloric acid, and so on.
When added to water, chlorine reacts to form hypochlorous acid and hypochlorite.
At pH levels between 3 and 6, hypochlorous acid dissociates poorly.
Simultaneously with the dissociation, hypochlorous acid partly breaks up, forming monatomic oxygen, which contributes to the oxidizing effect:
The actual agent is hypochlorous acid (HOCl) which forms when chlorine is added to water:
Bleaching powder bleaches by having its hypochlorous acid set free, which in turn gives up oxygen, being converted into hydrochloric acid.
It is true that such cases of isomerism are as yet unknown, but we do know that certain metals, in our present state of knowledge, yield oxychlorides only, while others only form hypochlorous salts.
In the case just now assumed we arrive at the oxychloride; when, however, the metal and chlorine change places in the water molecule, the isomeric hypochlorous salts are the result.
Fluorine possesses an odor which M. M.issan compares to a mixture of hypochlorous acid and nitrogen peroxide, but this odor is usually masked by that of the ozone which it always produces in moist air, owing to its decomposition of the water vapor.
