Why doesn't potassium ion K+ from KMnO4 appear in the following two unbalanced equations: MnO4– + C2O42– Mn2+ + CO2
MnO4– + Fe2+ Mn2+ + Fe3+ ?
The potassium ion is a spectator ion. You have written ionic equations (but omitted the arrows to separate the reactants from the products).
determination of the oxalate content in k2 cu(c2o4)2 .2h2o,
during standardization of permanganate solution using sodium oxalate,
can the titration between Mno4- and C2o42- at 25degree celcius be perform?
