| Abstract: | Equilibriun constant of oxidation reduction reaction between Fe(CN) -3 6 and vitamin C had been determinated by measure of the electromotive force of the cell.The result indicated that if pH=2.2 and t=25 ℃,then the electromotive force E=0.158v. and equilibrium constant k=10.It is proved that this method is fast and easy to use. |
