Synthesis of potassium trioxalatoferrate (volumetric techniquesand KMnO4 titration)
Work the following problems:
a. suppose you have as much 0.03200 M KMnO4 as you need. Stateexactly what data must be recorded in order to analyze a solid ofpotassium trioxalatoferrate for both iron and oxalate.
b. Describe the titration endpoint:
c. State the critetion for reading a buret filled withKMnO4:
d. A solution is 0.020 M in KMnO4. A student asked to prepare500.0 mL of Na2C2O4 solution, 25.00 mL aliquots of which will beused to standardize the KMnO4. If approximately 33 mL of KMnO4 areto be used in each titration, describe exactly how you wouldprepare the sodium oxalate solution. Show all calculations.
(M.W.: Na2C2O4= 134.0)

a we will start adding potassium permangnate in the solution of oxalte ion until we get the end point the point of completion of reaction Now we can calcualte the moles of KMnO4 required for completion of reaction as Moles Molarity X volume See Answer
