1. The problem statement, all variables and given/known data As in the photo 2. Relevant equations 3. The attempt at a solution i need ans for this whole question . my ans for part i ) is oxalic acid - dicarboxlic acid tartaric acid - 2,3-dihydroxo-1,4-dicarboxlic acid . for part c ) I used dilute KMNO4 to differentiate these 2 compounds . Oxalic acid will show positive result , which is CO2 ANH H20 formed , and purple KMON4 decoulorises.
