If I recall correctly, only anhydrous isopropanol forms peroxides, though I don't have a source for that. If you're really concerned, test it for
peroxides. It isn't that hard. Obviously don't distill to dryness, and follow all the common distillation precautions, but I wouldn't be to
concerned about peroxides.
Nuclear physics is neat. It's a shame it's so regulated...
Now that I think about it, that's probably a good thing. Still annoying though.

Hello all,
I am wondering if someone could give me guidance as to where in western Canada I could have a couple samples spectographically analysed? I am looking
for either Rahman or FTIR analysis, furthermore what range of cost would I be looking at?
Thanks for any help.

Hi all, I am crystallising out some potassium chromate, what liquid can I use to wash the crystals with minimal loss?
It's very soluble even in cold water, and it will react with alcohols. Would acetone or MEK work? Cheers.

In the wiki page for isocyanic acid it said 'isocyanic acid hydrolyses to carbon dioxide and ammonia' but didnt state the rxn conditions, does anyone
know what conds are needed, other than adding water?

Looks like anhydrous nickel sulfate. Pure anhydrous nickel sulfate looks as follows:

A clickbait answer....as are all of woelens pages..well i find anyway. Your site for home chemists is kinda like facebook, you open it for a reason
then three hours later not only have you not attented to the reason you looked there in the first place, you longer care about it as your interest in
other stuff has been piqued!!.
If someone hasn't complimented you lately woelen on your digital presence. Its pretty fucking excellent and has been for a very longtime.
Good one.

Just in case someone gets the wrong idea, there is none of the usual click bate or storm of ads or popups on woelen site or this site. Which is a
refreshing difference.
So yes thanks woelen and SM
I am wg48 but not on my usual pc hence the temp handle.

"clickbait" is a pretty damn disparaging word, sir.

status, nationality, citizenship, etc" z-lib

Regarding offence taken by my use of the clickbait word. I understand however...i ...was...using..it
in a metaphorical manner.....isn't english a great language.
Terribly sorry if my metaphor was shit and confusing (which it was). I was merely attempting to describe the captivating nature of the website.
And there ain't a single ad just lots of stuff about Jesus....(that was joke there's no stuff about jesus)

Better to say that 'Woelens site is good'. (including the stuff about Jesus). :-)
Thanks for the link way above Sulaiman.
Can anyone get me a phase diagram for the system KNO3, NaCl and water.
It does not appear to exist for some reason or other.

What's a reasonable wattage for a heating mantle? Is 300w reasonable for 250ml? What about 500ml or 1000ml?
Nuclear physics is neat. It's a shame it's so regulated...
Now that I think about it, that's probably a good thing. Still annoying though.

You need less power for heating mantles than for hotplates in terms of heating (1/2 the power, as a rule of thumb, or even less). I have a 100ml
heating mantle that is made from a 100W heating wire and it's very powerful. 200W should be more than enough for 500ml. I'd go for 300 or 350W for 1L.

Do bromide salts usually have a vinegar-esque whiff about them or should I be suspicious about this vaguely-acetic-smelling KBr?
