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?
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).
