I heat the filter and platinum salts from part five in hydrochloric acid to dissolve the salt. Then I filter out the solids, transfer to a clean beaker, and add a saturated solution of ammonium chloride. The ammonium hexachloroplatinate immediately precipitates out as a bright yellow precipitates that settles cleanly. I filter off the waste solution and capture the canary yellow platinum salt in a filter.
