Oxalate titration
WebScience Chemistry In acidic solution, sodium oxalate, Na₂C₂O4, is oxidized to CO₂ by MnO4. In the process, MnO, is reduced to Mn² + To titrate a 0.855 g sample of Na₂C₂O₂, 43.7 mL of an MnO solution were required. The same MnO solution is then used to analyze samples that contain uranium. A 12.8 g sample of a material that contains ...
