Aug 16, 2012·Gravimetryis the old technique for the recovery ofgoldsince the discovery ofgold. But recovery is the issue for the gravimetric determination. In literature there are several reducing agents reported, which reducesgoldfrom the solution like oxalic acid, hydroquinone, sulphur dioxide, ferrous sulphate, 2,4,6-triphenylpyrylium chloride ...
After solution, certain minor operations may or may not be necessary, but as a rule the next essential operation is that of precipitation. In his qualitative work the student has already come across many cases of precipitation, and he will find that many of the methods there used are again applied for quantitative purposes. Silver, for instance, is precipitated as the chloride AgCl, copper as ...
