Content
Getting
- In nature, the pinchit mineral, Hg 5 O 4 Cl 2, is found [1] .
- To a hot (50-55 ° C) solution of mercury (II) chloride , sodium tetraborate solution is added. Golden yellow or dark brown crystals form.
- When light crystals are heated to 180 ° C, black crystals form in an ampoule with nitric acid.
