Tharollo ea NaHS ea Metsi
Sodium sulfide nonahydrate (Na₂S·9H₂O) e qhibiliha metsing a sa tsoa hloekisoa ho etsa Tharollo ea Na₂S ea 13% (w/v).
Tlas'a ho hlohlelletsa le ka tlase 20°C, 14 g NaHCO₃ e ekelitsoe ho 100 mL ea tharollo ena, e bakang ho qhibiliha hang-hang le karabelo ea exothermic.
Ebe 100 mL methanol e eketsoa (ho boloka mocheso o ka tlase ho 20°C), e leng se etsang hore likristale tsa Na₂CO₃ li pompe.
Kamora metsotso e 10, motsoako o sefshoa, 'me masala a hlatsuoa ka 50 mL methanol.
Filtrate e na le ≥9 g NaHS le ≤0.6 g Na₂CO₃ (~3.5 g NaHS le 0.2 g Na₂CO₃ ka 100 mL).
