Igisubizo cy'amazi cya NaHS
Sodium sulfide nonahydrate (Na₂S·9H₂O) ishongeshwa mu mazi mashya kugira ngo ikore 13% (w/v) igisubizo cya Na₂S.
Munsi yo gukangura no munsi 20°C, 14 g NaHCO₃ yongewe kuri mililitiro 100 by'iki gisubizo, bigatera gushonga ako kanya no kugira ingaruka ku bushyuhe.
Hanyuma hongerwamo methanoli 100 (ikomeza ubushyuhe buri munsi ya 20°C), bigatuma kristu za Na₂CO₃ ziyongera.
Nyuma y'iminota 10, uruvange rurayungururwa, hanyuma ibisigaye byogeshwa na methanoli 50.
Filtrate irimo ≥9 g NaHS na ≤0.6 g Na₂CO₃ (~3.5 g NaHS na 0.2 g Na₂CO₃ kuri 100 mL).
