Question

suppose you have as much 0.03200 M KMnO4 as you need. State exactly what data must be recorded in order to analyze a solid of potassium trioxalatoferrate for both iron and oxalate.

Answer 1

You have to add KMnO₄ solution of known concentration to the solution of Oxalate
ion and wait until the reaction is complete.From the stoichiometry using the volume of
the MnO₄^- solution required for completion of reaction and the concentration of the
solution used (0.03200M) we can calculate mass % of oxalate ion present in our
sample. Now this when you compare with the expected mass % based on
compound's chemical formula, from this you can confirm or analyze for
both Iron and oxalate in Potassium trioxalatoferrate.
