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
This post gives information about Silver Chloride. Silver chloride is a chemical compound with the chemical formula AgCl. This white crystalline solid is well known for its low solubility in water (this behavior is reminiscent of the chlorides of Tl+ and Pb2+). Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grey to black or purplish coloration in some samples. AgCl occurs naturally as a mineral chlorargyrite. That's why I appreciate your content. After that I Will be busy making an assignment such as academic transcription for my education. Great work and good luck in the future.
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.
