WebApr 23, 2024 · Oxalate is a naturally occurring molecule found in abundance in plants and humans. It’s not a required nutrient for people, and too much can lead to kidney stones. WebThe purpose of this experiment is to prepare two of the many complexes formed between oxalate and chromium (III), examine some of their properties anddetermine the purity of the prepared samples. Note that oxalic acid is a mild reducing agent and is oxidised to CO2(g) by strong oxidisingagents like Cr2O72-, which is reduced to Cr3+.
