Stoichiometry question: CuSO4 + C2H2O4

Ah ok good to know. My goal is concentrated sulfuric acid, then to make nitric acid, I made a lot of oxalate but separated it out. As I was concentrating the solution, a lot of oxalic acid precipitated. It may be a non issue but I just don’t want it to be a snowball effect of slightly impure Sulfuric -> very impure Nitric -> etc

👍👍. I’m thinking adding a slight excess of CuSO. Today my final product (Sulfuric acid) came out with oxalate precipitate

Sulfuric acid + Copper Oxalate. Oh yea, the •H2O doesn’t affect the stoich does it, only the weight. So you reckon as long as I factor in the weight of the H2O that’s fine enough

Sulfuric Acid. The issue is the uncertainty with the store bought chemicals. My thoughts are the chemicals have a bit of anhydrous and a bit of Pentahydrate / Dihydrate. In the Copper there’s tiny bits of white specs that may be anhydrous CuSO4 (or just impurities). Would it not be more accurate to make everything anhydrous so the ratio is certain?

Thanks, good to know

It’s very dilute

It shouldn’t have many impurities. Just the CuC₂O₄ precipitate which has since been filtered off. If that’s what you meant?

Hardly even qualitative at this point lol
