determination of the oxalate content in k2 cu(c2o4)2 .2h2o,

Question

during standardization of permanganate solution using sodium oxalate,

can the titration between Mno4- and C2o42- at 25degree celcius be perform?

Answer 1

I don't know what the first paragraph has to do with the other two.
Yes, permanganate and oxalate can be titrated but it is extremely slow at the beginning. Mn^2+ seems to catalyze the reaction so the reaction is much faster after some Mn^2+ have been formed.
