Abstract
A new titrimetric method for the microdetermination of stannous tin, e.g., stannous chloride is proposed. The mechanism of the reaction in the presence of dilute hydrochloric acid is discussed. The determination of stannous tin is done on concentrations ranging from 10 mg to 100 μg. The experimental error does not exceed ±2%. Comparative analysis of tin sheets, rods, and foils by the proposed method and the iodine method is reported. The method has been shown to be suitable for the determination of tin in canned foods.
