Statistics for A simple, convenient and accurate gravimetric method for the determination of silver is presented. 4-Amino-3-methyl-5-mercapto-1,2,4-triazole precipitates silver quantitatively from ammoniacal tartrate medium. The complex is weighed as AgC<inf>3</inf>H<inf>5</inf>N<inf>4</inf>S after drying at 120-30°. Separation of silver from a large number of cations is described. Application of the method for quantitative analysis of alloys and complexes of silver is reported. The average relative error for the range 20-70 mg of silver is ± 0.25% and the relative standard deviation at the 40-mg level is 0.2%. © 1978.
