Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.
Author Name is a required field.
Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.
Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.
You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!
Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Bert,
I've never really used the salting-out method, but my understanding is that saturated NaCl solution is added to force precipitation of the NaClO3. The solubility of NaClO3 in water drops quite rapidly as the NaCl concentration goes up, so I'd imagine it just precipitates out to the bottom of the vessel.
It is really a way to force more NaClO3 out than you would otherwise get just by concentration and cooling. It is probably useful if you want to extract the most NaClO3 per run and collect it for use in a Perchlorate cell. Go too far however and NaCl will come out too; you won't have gained much "purity" if the desire was to keep the Chloride concentration low for your Perchlorate cell.
Regards,
Alan

Talking about the "salt out" method,will the sodium chlorate floats in top in the surface(because of water evaporation) or settle to the bottom, after adding sodium chloride to saturate it?
