Abstract
A method is described whereby antimony, copper and iron are reduced to their lower valence states by the action of titanous chloride in hot, dilute perchloric acid solution. A short period of heating suffices for the oxidation of the excess of the reductant by the perchloric acid, which does not affect the reduced antimony, copper and iron compounds. These are then determined by titration with suitable oxidizing agents. The method is rapid and precise and is subject to few interferences. It is possible to determine antimony and copper, or antimony and iron, in presence of each other, but copper and iron cannot be determined separately when both are present.
