What will take oxidation off brass without a lot of elbow grease?

They, [municipal utilities] are actually switching more to concentrated
liquid CL than powder. Larger utilities, and small ones have either auto fed or hand mixed the powdered Sodium Hypochlorite for years. Accidents with one ton CL gas cylinders cause mass evacuations.G Bugs |

The question is, what is Chlorine gas dissolved in water? Is it ionized, like it would be if you added salt to water. (salt is sodium chloride, so it has chlorine atoms in it) Or, does the dissolved chlorine gas remain in gaseous form, so upon heating the water, it would bubble back out? And what do they do when they add chlorine to drinking water to kill the bacteria at the water purification plant? Do they put some chlorine salt that ionizes in the water, or do they just dissolve chlorine gas in it, so that it dissipates out of the water after some period of time? The later is the conventional method. Yes it does come back out. That is what you smell when opening the tap. A newer method is using UV (ultraviolet) radiation to kill all the "little bugs". ...lew... |

Mustard is a blister agent, where chlorine is a choking agent. Other types of agents are blood agents like phosgene and hydrogen cyanide (and carbon monoxide) and nerve agents like sarin. The nerve agents, developed after WWI, are by far the most deadly. |

I remember having a tank of big $ fish and hearing the water company was
'thinking' of changing away from Chlorine - that meant that bottled water was required until they fessed up to what and the general group in town - clubs and stores agreed on the treatment and if one or two types of treatments were needed. We waited until the lines were flushed enough to start single treatment. We no longer have fish, but someday maybe.

Stand corrected - but now the world knows how to make the nasty gas.
Yes - not everyone signed the treaty - but will be held to human rights level.
