✦ Synopsis

Silver is frequently determined as the silver chloride. In the usual procedure10 * the silver is precipitated by the addition of hydrochloric acid, the precipitate filtered through a tared gooch, and the gooch heated in an oven to constant weight. It occurred to the author that it would be advantageous to filter the silver chloride through a filter paper, dissolve the precipitate in an appropriate solvent, and determine the silver electrolytically. This would increase the accuracy of the method by eliminating two errors -the error due to decomposition of the silver chloride by lightd, and the error due to the difficulty of removing the last traces of moisture from the silver chloride a 6. It would also be more convenient since it would eliminate the necessity of preparing gooches and drying gooches.
