title: Selective gravimetric method for direct determination of tin(IV) with N-o-toluoyl-N-o-tolylhydroxylamine and its application to brass and bronze analyses.
abstract: A selective gravimetric method for determination of tin(IV) with N-o-toluoyl-N-o-tolylhydroxylamine by direct weighing as Sn(C(15)H(14)NO(2))(2)Cl(2) is recommended. The metal complex, dried at 110-120 degrees , gives reproducible results. The method is simple, rapid and quantitative over a wide range of acidity (1-4N sulphuric acid) and is superior to existing gravimetric methods. The method works satisfactorily for determining tin in brass and bronze.
