Talk:Chromium(III) chloride

Changed "commonest" to most common. 24.156.180.185 03:24, 28 October 2005 (UTC)

I think this is another Brit. vs. US thing (I'm a Brit living in the US)- I have seen this type of edit a lot. The commonest form in UK is "commonest", the most common form in US is "most common." Even my "American Heritage Dictionary" lists "commonest," however! Walkerma 15:14, 28 October 2005 (UTC)

Image- hexahydrate?

The image shows chromium(III) chloride hexahydrate, which may be misleading. Chromium(III) chloride is more grayish black muddy thing. —Preceding unsigned comment added by 75.4.238.49 (talk) 00:28, 12 January 2008 (UTC)

Fair point. In our old style chembox, in which this image used to reside (see this example), there was an explanation that it was the hydrate. If you click on the image, or hover the mouse over it, you still get that. But I'll see if we can get something added to the new chembox to allow the image to carry a caption. In the meantime, if you can get a nice image of the anhydrous form (I don't), and you're willing to share it with the world, please upload it! Thanks, Walkerma (talk) 04:31, 12 January 2008 (UTC)

Done.

Dissolving of stainless steel

I dissolved a stainless steel ball in hydrochloric acid. It didn't dissolve readily but started reacting after it was heated. (It continued reacting after it cooled.) It formed at first the distinguishable yellow color of dilute iron III chloride, but started producing a green solution after a while. It couldn't have been copper, because copper doesn't dissolve in nonoxidizing acids. It might have been nickel, but nickel salts tend to be a lighter blue. It could have been a mixture of chromium chloride and nickel chloride. It had a yellow-green color. The color may be off because of the presence of iron III chloride. Any idea on how to separate the components?--98.221.179.18 (talk) 22:42, 3 March 2010 (UTC)
