ARTHUR AND DONAHUE~ originated the use of electrogenerated titanous ion for coulometric titrations, and applied the technique to the determination of ferric ion. They employed a gold generator cathode, a supporting electrolyte composed of o.4111 titanic chloride in 0.711P hydrochloric acid, and titrated 50 to 1x0 mg quantities of ferric ion with an average accuracy of about &0.3% Our experience indicates that the actual current efficiency for titanous ion generation -as distinct from net titration efficiency -in a solution of hydrochloric acid as dilute as 0.7111 is much smaller than IOOO/~, and the high net titration efficiency observed by ARTHUR AND DONAIIUE
