Solubility of various chemicals
Solubility for the following, please:
Maltodextrin
Silicon dioxide (the type found in pills)
Aminoguanidine hydrochloride
I need aminoguanidine salts for synthesising tetrazoles, but the usual aminoguanidium bicarbonate synthesis is a very long process and I am
challenging myself to synthesis azidoazide azide (1,1-azobis(tetrazole)) from OTC materials.
I can't think of a better signature.

Silicon dioxide is insoluble by any standards.

Thanks. So is magnesium stearate. And from what I know, maltodextrin is only capable of forming a suspension with water. Is aminoguanidine
hydrochloride also insoluble (hopefully, it isn't.)
I can't think of a better signature.

Are you getting this from a pill? What pill contains aminoguanidine HCl?

Why not just open up an account with Sigma Aldrich and order from them? Saves the hassle of dismantling gelatine capsules, lol!

Sigma Aldrich Sells according to a System/Procedure.
Fundamentally they are a sales outfit, just with some restrictions on Who they sell to, What they sell, and in what quantitity.
As with all Systems, figure out how that system works, then approach it along the correct line that will not cause that System any concern, and it
will operate according to it's design.
Ebay is a lot easier.

IPAmine with Cu(II) perchlorate --> of course.
Did you meant HMTD (hexamethylene triperoxyde diamine) or HMTA (hexamethylenetetramine)? I think that once again you did confuse the two!
What complex with Cu(II) perchlorate?
The one from Laboratory of Liptakov? Then it is HMTA!
--> Think twice³ before posting!

A good thermite composition here:

20% acetone peroxide
10% azidotetrazole
10% neat hydrazine
Get what I mean?

Stop doing this!
The two first ingredients are indeed a thermite...
But the rest is wrong info (misinformation) to make someone innocent hurt himself...and set the surrounding in fire because of the gaseous blast of
incandescent molten metallic drops...

If you don't say in what solvent and under what conditions, hard for someone to answer!
Silicon dioxyde is soluble in HF, in NaOH, in N2H4, in concentrated Na2CO3 and some form (Si(OH)4) into water.
SiO2 is soluble in molten Al2O3...

Silicon dioxide is soluble in hydrazine? Sez who?

NaOH + H2O2 - smell emitted - WTF is it!?
I mixed some ~30% H202 with a 50/50 NaOH/H2O solution. A frothy white foam formed in a vigorous exothermic reaction. The smell that was emitted is
pretty vulgar and triggered my gag reflex, pretty severely. Any idea what the cause of the smell may be? I have no problems with mixing strong NaOH
solutions (gives off smell for sure) nor do I have a problem with sodium salts in general. Ideas?

How safe would Th(ClO3)4 flash powder be?
We are thinking of making a bit of thorium chlorate.
Would setting off a small amount of thorium chlorate-magnesium flash powder be extremely dangerous?
We were concerned about the radioactive smoke that would likely be produced.
Any suggestions wellcome

Seriously, why?
Thorium is difficult enough to get hold of -- I have no idea why you would want to perform a reaction where you could not recover it. As for
releasing it into the environment: particularly in a finely divided form that could be breathed in -- I would not even consider it. I am not sure the
exact consequence of breathing in radioactive thorium, but it is not something that is on my wish list.
If it is more than a curiosity -- that is, you want to do some actual science...
set off your flash powder in a closed vessel under vacuum with a filter to catch all of the product. Perform a before and after with a geiger counter
to make sure all your thorium is where you think it is. Plan how you will reprocess it and calculate the yield / losses at each stage.

Sounds like more trouble than its worth. We were just curious what it would be like.
We dont think we'll try it now. You make a good point, the thorium is hard to come by.
It would be a wast.
But Purerly theoretically, do you think the flash powder would work?
We gather it would based on the last section of your post.

Dunno.
I would want to think about the reactants and products carefully and work out if it is thermodynamically viable. I do know that thorium-anything
converting to metal is a serious uphill battle. But I don't really have any idea about chlorates in this context.
Paging blogfast25. He would know: and probably without looking anything up.

What is the pH of periodic acid? I have found some for sale at OnyxMet, and I want to try some simple reactions with it.
NaAcetate + metaperiodic acid = sodium periodate + acetic acid. Rubbish or not?

The CRC gives its Ka as 2.3e-2, which is fairly strong. Acetate ion should deprotonate it readily.

Does manganese (iii) oxide (Mn2O3) react with hydrochloric acid?
I can't find any information on this.

Depends on how well-dried it is. If it's fresh, it will react easily. If it's calcined completely, then it's a rock.

Why is it that there are a lot of organic nitrates (nitrotoluene, nitrobenzene etc.) but virtually no chlorates of the same ilk? This interests me.
