Making anhydrous sodium sulfate (Na2SO4)

In this video you will learn how to make sodium sulfate (Na2SO4) from sulfuric acid (H2SO4).

[@chemicalmaster3267]

Sodium sulfate actually has a weird solubility vs temperature behaviour. Besides having lower solubility below room temperature it also has lower solubility near the boiling temperature of water.

[@THYZOID]

Nice! Didn’t know that before.

[@chemicalmaster3267]

@@THYZOID Try to find a solubility table for sodium sulfate to see what I mean. if you´re curious you can also experiment with your sodium sulfate and see its temperature vs solubility behaviour yourself.😄

I know this is a older post but im going to share my story any ways for safety reasons. I had cleaned some drain cleaner sulfuric acid with hydrogen peroxide.i watched that procedure on a nerd rage video i believe.i was left with a almost about 60/40 sulfuric/h2o2 solution thats been sitting on a shelf for awhile. Ended up coming across this video and figured that solution would be awesome to use in this reaction where its already deluted. Well i decided i was going to double this reaction 112ml sulfuric and 160g sodium hydroxide.i end up using 150ml h20 so make a solution of the s.hydroxide.beaker in a ice bath already i proceeded to pour a little bit of the 120ml sulfuric acid into the hydroxide solution and ya the second the first drop hit the entire content of the beaker exploded every where covering myself and my work space in this concoction. Thank fn god i had for whatever reason decided to put on a tyvax suit and my respirator.i almost didn't wear any of it because things went so smoothly in this video. Let this post be a warning to always ALWAYS wear safety gear when learning/working with any reactions.i really almost covered myself with acids and base.my suits was literally dripping and i have a good feeling when i go back in there itll be partly decomposed. Im not sure if this happened because of the sulfuric wasn't deluted enough or if it was because there was peroxide in it.i figured the sodium hydroxide would destroy the h2o2 like when storing ethyl acetate over sodium hydroxide. Morale of the story even if it seems silly never ever attempt to do any reactions without proper safety protocols

[@erickwalker11]

That's exactly what happened.... make sure and very sure after you apply the hydrogen peroxide you distill the sulfuric acid clean before tossing it in hydroxide lol

[@ericami5642]

Funny my name is Eric too

[@Daboresa]

Hydrogen peroxide is highly oxidizer you should have at least dilute your Sulphuric acid

[@kamelsamer5768]

0:26 face back, ready to run hahaha

[@midwestchem368]

At least in my experience I always added the base to the acid which implies sodium bisulfate is produced first. Maybe its my reagents but there has always been a very small but noticeable color change when the bisulfate converts to sulfate.

[@BackYardScience2000]

Nice prep! I love reactions like this.

[@THYZOID]

Some plain and easy chemistry. Nearly nothing can go wrong and you get a 100% yield. Great stuff😁

[@hanleypc]

Interested to see what you've got planned for the Sodium Sulphate as I thought it wasn't very useful.

[@THYZOID]

It’s a great drying agent even under highly acidic conditions. I already filmed a video with it and sulfuric acid which is yet to be published.

[@chemicalmaster3267]

@@THYZOID Sodium sulfate actually combines with sulfuric acid to form sodium hydrogen sulfate a.k.a sodium bisulfate.

[@hanleypc]

@@chemicalmaster3267 Interesting, taking the hydrogen from the water present and so concentrating the H2SO4 that is in excess?

[@chemicalmaster3267]

@@hanleypc No. Sulfuric acid has 2 acidic hydrogen atoms (protons) so depending on the stoichiometry it can form either sulfates ou bisulfates when neutralizing bases. Sodium sulfate reacts with sulfuric acid to form sodium bisulfate: Na2SO4 + H2SO4 = 2 NaHSO4

Little confused, 250 degrees centigrade in an oven or what? You're gonna have to excuse me, I have not slept in about 3 days now cause just found out I have Lukemia so I've been noticing that my attention span is all over the place, so pardon me!😊

[@1BobTheSubGenius]

Pretty much anywhere you can get the right temperature I think, so technically can be a oven, or a hot plate, etc

[@SodiumInteresting]

Could the anhydrous sodium sulphate be distilled with potassium nitrate to easily produce red fuming nitric acid? Or can it only be done with sodium bisulphate? 🤔 Tom

[@THYZOID]

That would require sodium bisulfate. NaNO3 + NaHSO4 --> HNO3 + Na2SO4

[@SodiumInteresting]

@@THYZOID that's what I suspected. A shame the anhydrous form needs 300° to melt

[@muratkural735]

Damn I don't have an oven I can use, errgh I do but it's um the wife's! Well does it stink badly when finished in the oven?

hi, can you make a video about making sodium/potassium, i've been trying to do this experiment

[@THYZOID]

Actually planned it. We have to get the tertiary alcohol first though.

[@emmanuelnah-4551]

@@THYZOID i followed NurdRage's method , no need tertiary alcohol

[@THYZOID]

His method is great. I wanted to do something different though involving tert butanol.

[@AbdHuz-24]

I have a 15% w/v na2so4 solution. At what concentration / temp , will ot crystalize ?

[@THYZOID]

There are tables online for that (search for solubility/temperature tables). It’s likely that it won’t crystallize without a seed crystal or that it’ll freeze completely before crystallization even takes place at suck low concentrations.

[@YouMockMe]

Even put a label on? +1 lab skill

[@THYZOID]

Well labeling is important.

is it possible to make Sodium Sulfate (pH 7) from Nacl & H2S04?

[@conceptofeverything8793]

You dont need H2SO4. SO2 will do just fine. I think its called the Hargreaves reaction, but Im not sure how it was conduced first.

yes
