Yes, there was undoubtedly some water in the residual extract. After it was evaporated, there was a tiny bit of salt in the crucible. I'd say by looking at the ammount of salt, I'd guess there was probably ten percent water, maybe more maybe less I couldn't weigh it.
I'm very aware that there are only ~180ml of acetic acid in a gallon of vinegar. Though, that hasn't stopped bees from neutralizing an entire gallon, evaping a gallon of H2O off, then drying the salt, liberating the acid, etc.
It was just a reminder of a simpler method for those who might want some quick acetic acid.
I never said GAA, but a quicker route to acetic acid. I'm just saying that in the time it usually takes to obtain a salt, one could have extracted the crude acid and continue on to make it glacial. Just quicker and less of a mess.
Vitus- Why? Will SO3 react with the acid? I figured it would react with water first to make H2SO4? Am I wrong?
Oh woops!! I see the error now. I made an error up there when I edited the post. I was thingking of the sentence where I was knocking the salt and accidentally put it in the end there. I meant to say drying over another salt then distiling over SO3....
Like anhydrous MgSO4 then distilling over the trioxide. THough for all practical purposes that isn't most peoples cup of tea. Making SO3 especially for this is quite impratical and would definately lead to a purchase.
I jsut said it cause I make my own H2So4 from pool chems and I have some laying around anyway. So of course it may just be more pratical and easier to just indeed make the salt and distill over sulfuric acid., or one could simple buy it like any sane person should
Though it still comes up here so much.
