Hi GREAT forum , i have been doing lots of reading and am taking slower steps now .After dissolving a watch casing in nitric acid all that remains is the gold foil .should i filter this and then put the foils into solution or boil off the nitric acid first before putting gold into solution.My idea being that i could boil the nitric solution to save time later as boiling the gold solution is not recommended.( filtering the solution once i have gold dissolved in aqua regia) and then evaporating the exess nitric acid out of the solution .Many thanks in advance!
