Can i use a different acid in this confirmatory test?

I found a confirmatory test for oxalate which uses sulfuric acid, but for my chem project we only have .5 m acetic acid, and various concentrations of HCl with the highest being 6 M. I will paste the confirmatory test i found, but the question is can I sub HCl for sulfuric acid? I have a several other compounds at my disposal as well if any of you know of a different test altogether. thanks.
