Thanks again for your patronage in making videos like this possible.

Outta curiosity, would you like me to dissolve gold with chlorine gas?

Dissolve Platinum with Chlorine Gas

In this video we dissolve platinum using chlorine gas in hydrochloric acid. A more cost effective alternative to the more common mixture of nitric acid and hydrochloric acid or "aqua regia". To do this we simply place a vial containing a mixture of hyrochloric acid (3mL) and platinum metal powder (337mg) in a jar along with three other vials containing trichloroisocyanuric acid (3g) and 10mL of water each.

Most definitely

Interesting as always :) But, høw much extrå do people with strånge lætters in their name dønate to get you to have correct encoding in your videøs? ;-)

I'd actually like to get that right, but i'm not sure how. The fonts don't seem to work properly with additional letters in adobe premiere pro CS5. I suppose i could manually draw the characters in photoshop and then past them in. But that would create a huge amount of extra work per video since it has to be redone every time. I'm still trying to figure it out.

Actually, I think it is a encoding problem. The "Bærulfsen" you see in the video is what you get if you try to encode UTF-8 text as UTF-8 text -again-, aka. "double encoding". I have no experience with Premiere, but there might be some encoding related settings you could play around with. For Norwegian names, like my own, substituting "æ" with "ae", "ø" with "oe" and "å" with "aa" is acceptable. Anyway, it is not important for me; I pay because I like your content, not to get my name in the videos :)

What's wrong with bubbling the chlorine gas thru your reaction vessel via a glass tube and a chlorine generator? It's very simple to set up with a few round bottom flasks and a pressure equalized funnel, some tubing connected to the vacuum take off, and a glass tube leading into the reaction vessel sealed thru a thermometer adapter. You can recycle the excess chlorine or lead a second tube away to your fan in your hood. Or work outside.

Well yeah. Poor choice of wording on my part. I meant why would amateur refiners shy away from using Cl2? If someone is serious about refining then it seems like it would be worth the minimal effort to learn how to set up a gas generator.

I'm not sure that the effort to learn is the limiting factor here. I'd personally be very leery about messing about with Chlorine Gas myself as my experience with chemistry (beyond a chem class in college in the mid 80s) is rather scant (to say I'm a rank amateur would do a disservice to REAL rank amateurs). Safety is a very large consideration for me, and as I don't have access to such luxuries as full labs or fume hoods, and I live in a fairly densely crowded apartment complex, doing things outside may not be an option when dealing with Chlorine gas.

Roger, fair enough. Chlorine, and bromine still make me nervous. Even working in a hood.
