Title: Oxalates reacting with sulphuric acid?
Post by: cas on March 05, 2020, 01:52:39 PM

Hey! I'm having a problem finding any information about whether oxalate anions react with sulphuric acid, or not. Thus far I only came up with something such as:

C₂O₄^2- + 2 H⁺  :rarrow: CO + CO₂ + H₂O

but, I'm not sure whether it's actually correct. Do you guys know, if the reaction actually happens? And if so, is the reaction above right or am I very wrong? Only sources I found use potassium permanganate in the reaction, however my task does not include it. Also, don't know if it's important, but the source of oxalate ions in this reaction is ammonium oxalate. Thanks for your help in advance!

Concentrated sulfuric acid extract water. So this reaction will happen. In diluted solution nothing happens.
