Tin(ii) Chloride Stannous chloride; SnCl2,2H2O = 225.6 (10025-69-1)

Analytical reagent grade of commerce containing not less than 97.0% of SnCl2,2H2O.

Assay Dissolve 0.5 g in 15 mL of hydrochloric acid in a ground-glass-stoppered flask and add 10 mL of water and 5 mL of chloroform. Titrate rapidly with 0.05m potassium iodate VS until the chloroform layer is colourless. Each mL of 0.05m potassium iodate VS is equivalent to 22.56 mg of SnCl2,2H2O.
