How to determine the solubility of compounds in H2SO4.

Hilski - 23-5-2012 at 11:42

I need some pointers on how to go about calculating the solubility of compounds in H2SO4. Mostly, I would like to be able to learn how determine the volume of dissolved sulfate salts of Ca, Fe, Mn, Mg, Na etc, as well as (NH4)2SO4 in ~93% and ~60% H2SO4 which are solutions saturated with the given salt. This is probably a pretty basic thing for most of you, but I'm still trying to figure it out.

Thanks in advance.

It would be very difficult to calculate the solubilities. You should use a table of data. I do not have access to such a table, but I'm sure other people do. Try searching around and you might find something.

This paper looks like it might have some info that would get me pointed in the right direction. Does anyone have access to this?

COMPOUND FORMATION AND SOLUBILITY IN SYSTEMS OF THE TYPE SULFURIC ACID: METAL SULFATE.

Here are a couple of useful related resources I have come across


Solubilities Of Inorganic And Metal Organic Compounds Vol I (1940/00/00) 1600 pages

This next one is basically just a huge list of references and databases that contain solubility data.
Solubility data in physicochemical data collections and data banks
iupac.org/publications/pac/69/5/0943/pdf/

References for solubility data of inorganic compounds from archive.org

Sodium bisulfate is not very soluble in sulfuric acid because of the common ion effect.

Thank you very much, DJF90.

Just FYI for anyone who cares:

I've been able to find pretty much all of the info I was looking for in the first link I posted to the Ebook
"Solubilities Of Inorganic And Metal Organic Compounds Vol 1".

For example, a solubility table for MnSO4 in aqueous H2SO4 is on page 1007 (1018).

This is a very thorough book, and should be helpful for just about any inorganic compound you can think of.
