Synthesis and Analysis of a Ferric Oxalate Salt - Odinity

The theoretical yield is calculated by using stoichiometric ratios to determine the amount of ferrioxalate that would theoretically be produced from the exact amounts of iron (III) chloride hexahydrate and potassium oxalate that were measured from the beginning of the experiment. The percent yield is then determined by the following equation:
