The amount of oxalic acid (?2?2?4) in a sample of rhubarb was determined by reacting with ??3+. After extracting a 10.62 g of rhubarb with a solvent, oxidation of the oxalic acid required 36.44 mL of 0.0130 ? ??3+. Calculate the weight percent %(w/w)of oxalic acid in the sample of rhubarb. 2 Fe3+(aq)+ H2C2O4 (aq)+ H2O(l)------> 2 Fe2+(aq)+ 2CO2(g)+ 2 H3O+(aq) Clue: the goal is to find the number of grams of oxalic acid reacting with iron so that you can divide it by the weight of the rhubarb sample to determine the weight percent.
