Tharollo ya Sodium Bicarbonate: Tsela ya go ya go Sodium Hydrosulfide

E se nago meetse sodium hydrosulfide ya go swana le yona

E lokišitšwe bjalo ka ge go hlalošitšwe ka mo godimo ka fase ga maemo a thata a go hloka monola.

Tharollo ya NaHS ya meetse

Sodium Sulfide ya sodium nonahydrate (Na2S·9H2O) e hlapolotšwe ka meetseng a sa tšwago go hlwekišwa go dira a13% (w / v) Tharollo ya Na2S.

Ka tlase ga go hlohleletša le ka tlase 20 ° C, . 14 g NaHCO3 e tlaleletšwa go 100 mL e le ya tharollo ye, go hlola go phatlalatšwa ka pela le karabelo ya exothermic.

100 mL methanol e gona e tlaleletšwa (go boloka themperetšha

Ka morago ga 10 min, motswako o a sefiwa, gomme mašaledi a hlatswiwa ka 50 mL ya methanol.

Sefiltara se na le ≥9 g NaHS le ≤0.6 g Na2CO3 (~3.5 g NaHS le 0.2 g Na2CO3 ka 100 mL).

Sodium hydrosulfide cha moromelantle, ya data e fumanehang, tobetsa mona ho fumana disampole mahala.
