what is your problem here? iirc, the solution stays yellow and of
course the crystalls stay in the filter paper.
iirc, the only tricky thing is to not over acidify in the end.
(i always thought this filtering step is quite wasteful. the yellow
crystalls are a mercury salt, maybe one could add those to the next
reaction?)
