In the titration of $KMnO_{4}$ with $C_{2}O_{4}^{2-}$,which temperature range is not proper? Why?
(N/A) The titration of $KMnO_{4}$ and oxalate is not performed at room temperature; instead,a temperature range of $50^{\circ}C - 70^{\circ}C$ is maintained. At room temperature,the rate of reaction is extremely slow,and the reaction is autocatalyzed by the $Mn^{2+}$ ions produced during the process.
