Hi Sam- I inquart and end up with Silver Nitrate that I add HCL to convert it to Silver Chloride- I end up with several buckets of it - What is the best way to fully rinse the Silver Chloride before my converting to metallic silver using the formic acid technique ?
I've looked at the larger size table top Buchner Vacuum filters that SP Bel Art makes, pulling a vacuum on it and pouring hot water over it until the run off is clear = but I'm not sure there might be a better way then using one of these-
Thank you -
Art
hello
Thank you Sam -
P. S. For every wash cycle there must be a vigorous stirring and agitation.
Hi Art, First thing first. Be advised that for higher grade silver, about 5-8 boiling hot water rinses are required followed by one or two hot dilute HCl washes and then two more boiling hot water rinses. To seperate the washes from the AgCl; There are three main methods. First would be simple gravity method where you would just wait as much as needed for the solids to settle and decant. The cleaner the AgCl is, the faster it will settle. Vacuum filtration as you mentioned. Third woul be to use a centrifuge. I would opt for the gravity method.
