Overrun with sal mirabilis!
Here in my lab, I'm wading knee deep in sodium sulfate. I get this as a side product when I extract NaOH from a dry alkaline drain cleaner. Lots of
sal mirabilis. Metric craptons of sal mirabilis. And I don't know what to do with it.
Okay, I can:
* Make alums;
* Dehydrate the salt by calcining and use it as a desiccant;
* Convert it to bisulfate and use that for making oleum;
Who knows what else one can do with sodium sulfate?
Smells like ammonia....

Take it,if you cant take a dump.
Seriusly, there arent a lot of things this is useful.
Maybe you can convert it into NaOH by Ca(OH)2.

^Seriously I don't know why that guy even posts
But about the sodium sulfate, if you have an impressive enough heat source, you can try carbothermal reduction with charcoal to yield sodium sulfide,
which can be quite useful. Apart from that, you can just dry it and use it as a desiccant.

I use small amounts of Na2SO4 to dry organic liquids.
Making NaHSO4 sounds like a good idea. Use it for the following:
1) Use for oleum, as you say.
2) I use it for making gaseous HCl: NaHSO4 + NaCl + heat = a controlled source of HCl gas.
The single most important condition for a successful synthesis is good mixing - Nicodem

If it's pure enough, just bag it and sell it or trade it for other chems..........................?

Good thinking CJ.
Skip the 'pure enough' part and sell slightly bigger quantities for slightly less $ and corner the market.

You could use it to store quite large amounts of heat. For instance, to heat your house overnight with solar power collected during the day.

Na2SO4 used to be used as a laxative if anyone was confused by his original post

Still is sold as a laxative.
Isn't called 'Miracle Salt' for nothing 
The marketing should be updated for modern terminology.

Correct me if I'm wrong, but as far as I know that salt can be used as a water softener, isn't it what is added to washing powders for the same
reason? Also, how did you separate NaOH from there and what kind of drain cleaner is it that contains sulfate - what for?

papaya, in my country there is a drain cleaner brand "KROT", the ingredients are NaOH and Na2SO4. The separation is very simple: it is physical. NaOH
is in granules, Na2SO4 is in small crystals. Dry gauze cloth does the trick.
Smells like ammonia....

Speaking Hungarian is easy.Speaking properly is not. Some adults have problem with it. Another lang. and everything is screwed up in your brain.

Recrystallise it as the decahydrate and use to to check your thermometers.

do nothing, your next process maybe need this "Lots of sal mirabilis. Metric craptons of sal mirabilis.", so store in a right container and place and
or not, sell it.
the most wise is before start something have an idea of bi-products undesirable and their management.

One method of recycling sodium sulfate is to electrolyze it to produce sodium hydroxide and sulfuric acid. This is important in the paper industry
which generates it by the kiloton. It requires a membrane cell similar to a chlor-alkali cell but works best with a modified membrane. Three
compartment cells are also used which produce a more pure product.

You could try to use sulfate for salting out several organic solvents from their mixtures with water like alcohol/H2O , acetone/H2O (in case you make
your own alcohol or such), however I don't know how effective it is.

Here is an equation (see https://books.google.com/books?id=GukWyQnHW6wC&pg=PA479&...) that suggests to me a possible path to bisulfate by taking heated Na2SO4 and
treat with steam and chlorine:
Na2SO4 + Cl2 + H2O = NaHSO4 + HOCl + NaCl
The volatile Hypochlorous can be evaporated off (with some gaseous Cl2O) leaving an ionic (from the added NaCl) Sodium bisulfate fit to use as a
toilet bowl cleaner (like the once known product called Vanish, please see this interesting list of ingredients at http://householdproducts.nlm.nih.gov/cgi-bin/household/brand... ) for sale or personal use.
In my opinion, the reaction is likely reversal as:
H+ + Cl- + HOCl ---) Cl2 + H2O
so reaction conditions/mechanics could impact yield.
An alternate preparation would be to place Na2SO4 in chlorine water in a sealed vessel in sunlight with periodic shaking. The photo decomposition of
the hypochlorous acid forms HCl (along with oxygen gas and possibly some HClO3 as well) that could react with more Na2SO4 to produce the desired
NaHSO4/NaCl on evaporation with a touch of chlorate.

I'm just boiling it with conc sulfuric. It dissolves and turns into an easily melting salt that has to be bisulfate.
Smells like ammonia....
