Direct Titration of Ferric Iron by Stannous Chloride

Abstract

ASA standard stannous chloride solution may be stored without difficulty, the reaction 2FeCl3 + SnCl, = 2FeCl2 + SnCh may be used as the basis of a method for the determination of ferric iron. It is not only possible to carry out the reduction needed

Inorganic Volumetric Analysis

“…Metallic iron in ores is also determined by permanganate titration following solution with copper sulfate (205). Direct titrations of ferric iron include those with mercurous nitrate- (67,236), with stannous chloride (196), with a double indicator of thiocyanate and ammonium molybdate (221), and with titanous chloride (11,69).…”
