RE: ferric oxalate

It is REALLY quite easy to make from scratch. But it does take some time and does save a BUNCH of money. I also HIGHly recommend mixing the Potassium Oxalate from component chems and save even more money. It too is easy.  

 

Yes, you can heat the water too much. Heat will turn your ferric to ferrous before you have a chance to use it.

Oh, lord no. Not for a minute would I attempt to make anything from scratch-- except maybe a pound cake.

No, I'm just trying to mix up the ferric oxalate powder with distilled water and would like to know the amounts to use-- water to powder, and can you ever heat the water too much? Just having a hard time here, so wonder if I'm doing something wrong (as usual).

 

Thanks, Neal.

You are trying to make Ferric Oxalate from scratch? I've always been told this was a difficult process because of the compound's instability. There are detailed instructions at http://e.neilsen.home.att.net/FerricOxalate.html I've read again and again that this was something to buy rather make because of the time it takes and that the relative cost savings is neglible.

Did I misunderstand your question?
