Forgot about this thread... Anyway:
Chloroform synthesis, (I did this today), bromine isolation, potassium chlorate synthesis and I'm working on sodium chlorate right now. I've done
quite a few other experiments in the last few months, most of which I've forgotten.

I produced a good bit of Barium Carbonate, rather useful for barium compound making.

How'd you make it? Double displacement of barium nitrate and sodium carbonate is how I generally make mine.
I'm making copper (II) chloride right now.
Cu + HCl(aq) and H2O2 very nice color(s).
My sodium chlorate cell is still running, it's taking much longer than I thought.

Yes, that's how I made it.. Actually with bicarb. I made some of it's sulfate thinking I could get carbonate from that (barium nitrate & epsom
salt) by adding bicarb to IT, but I didn't realize how unreactive barium nitrate was.
I made some copper chloride a while back, but I had no HCl, so I used CaCl2 instead.
Is this the first time you've done a chlorate cell? What are you using as a power supply?

It's my first sodium chlorate cell.
I've ran quite a few potassium chlorate batches.
I am bought a power supply exactly like this:http://www.circuitspecialists.com/5-volt-30-amp-power-supply... except it pulls 20 amps, not 30. Got it from the same place though, don't know
where the one I bought went.
It has two terminals, one puts out 7 amps, the other 13. I'm just using 7 right now.

Wow, mine is a repurposed computer PSU, with a 7A max (At 10v, inconvinient, so I normally run it at 3A 5v)

There were many of them.. preparation of benzoic acid from toluene, methyl benzoate synthesis, ethyl acetate synthesis, piperine extraction, many
copper complexes preparation and the simple ones I am not going to mention.

basic ones, with ammonia, chlorido ligands, copper aspirinate and then I started to work with compounds such as..

Looks like fun, I love copper complexes. Those last ones look exquisite! I wouldn't have half the chemicals to make them, but... What colors are those last ones, copper aspirinate and the pictures?
I made some basic chloro complexes, but found a good salt to use for making Amminechlorido (I prefer Amminechloro) copper complexes, Ammonium Chloride
 . Works awful well, I'm pretty sure I made Amminetrichlorocuprate(II) acid
(3NH4Cl + CuSO4 >> H[Cu(NH3)Cl3] + (NH4)2SO4). The substance had a
pH of about 4 or 5.

Why are you pretty sure... Have you isolated and characterized the product you think it may be in some way? What is about nomenclature, in our country
we switched last year from chloro, bromo.. to chlorido, bromido.. The complexes I did - [Cu(NH3)4] and copper chloride
dihydrate, copper acetate, copper bis(oxalate) maybe could be interesting salts as copper benzoate, copper citrate, .. The structure I posted is
prepared by reacting potassium hexacyanidochromate with copper complex of compostion as follows [Cu(L)]SO4 . xH2O
and copper aspirinate picture..

Very pretty. With the 3NH4Cl + CuSO4 >> H[Cu(NH3)Cl3] + (NH4)2SO4
reaction, I'm only partially sure because I don't have a scale, and multiple complexes could have formed
I prefer chloro to chlorido, but I guess the second makes sense. It does add a second syllable, though.

Not exactly an experiment, but I had two 250 mL filtering flask, which is a very small volume and filtering was a pain in the A for me... So I took
one and made this, it looks very random but it does work well and I now have a 4 L filtering flask :p The green stuff is an epoxy resin which resists
to acids, oxidation and bases and the bottle is in HDPE. It is very solid. The only issue is that the HDPE bottle tends to collapse a bit under the
vacuum but as long as I am careful It works fine and hey, it is still better than having two 250 mL filtering flask, one being useless. It really
looks like it was made by a child though, it's quite funny :p

Smart Idea! I like it! To "how much vacuum" will the bottom hold up, do you think? Enough for filtering?

Enough for filtering, I tested it and it worked The top and the bottom are
actually very tough, there is only the middle of the bottle that twists a bit.

I'm confused, did you drill a hole in a glass flask? Or is it plastic?

Cool, you got your flask from Home science tools! I get stuff from there too!
That flask is from HST, it's glass. It looks like the glass has been broken at the bottom, and the green stuff is some sort of polyeth. glue.

I drilled an hole in the bottom of the flask with a rotary tool and a diamond dust head. and "The green stuff is an epoxy resin which resists to
acids, oxidation and bases".

Nice, I should get one if those. That or a tungsten carbide bit, either works for glass. Must've been pretty expensive, for one that big.

It was very small in fact, I just cut a circle, it took a bit of time but it did the job.

Guys-
I think the title should be "successfuly replicating procedures"? You're mostly talking about replicating someone else's experimental procedure?
A successful experiment is one that you obtain new information from, and possibly can draw some conclusion from... Even if the outcome is not what
you'd predicted. A negative answer is STILL valid information, even if it hurts the ego a bit. No is every bit as meaningful an answer as Yes-
http://en.m.wikipedia.org/wiki/Cognitive_bias
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

If you need one, sciplus.com has them cheap. I've never bought one from them, but looks like a good deal to me (Sorry, o link to the actual product,
use their search if interested).
