Chlorine, Cl, 17, is the second most reactive element in the halogen group, it's only out-done by fluorine. Physically it is a green-tinted gas, which has a sharp smell due to it's toxicity.

Chlorine is a well known word to most people, but you might be thinking of bleach, or a swimming pool additive. Neither of these contain any pure chlorine, and what chlorine they do have makes up less than 10% of the total mixture. If you've ever seen bleach take all the color out of clothes, or seen it turn cloth into a pure white crumbly mess, you probably have an idea what chlorine can do.

Pure chlorine is much more harmfull than that, if a jet of chlorine is aimed at a piece of paper it will stain it brown in seconds. Pure chlorine gas doesn't have many uses, at one point it was used as a gas weapon in world war I, but this use was internationally banned soon after.

Pure chlorine can be made by a reaction of calcium hypochlorite and hydrochloric acid, however both of these are very nasty chemicals, and the result if mixing them is nastier still. I don't plan on keeping alot of chlorine around, but I would like to have enough to be able to see its color.

These are my samples!

Gas Ampoule Set

This is a set of miniature ampoules I made to contain some of the more easily-acquired gases in the periodic table, in order from left to right, Chlorine(made from pool chemicals.. Very dangerous), Nitrogen(Just air.. 78% pure, not bad), Oxygen(Made from electrolysis of water), and Hydrogen(Made from electrolysis as well).
