Gin ma ki lwongo ni Sodium Bicarbonate Solution: yoo me nongo Sodium Hydrosulfide

ma pe ki pii sodium hydrosulfide

Ki yubu kit ma ki waco kwede malo ni i te cik ma pe ki yamo iye.

Gin ma ki lwongo ni Aqueous NaHS Solution

Sodium Sulfide nonahydrate (Na2S·9H2O) ki keto i pii ma ki yubu anyen me yubu13% (w/v) Na2S solution.

I te buru ki piny 20°C, 14 g NaHCO₃ ki medo i kom 100 mL me gin ma ki rubu ni, ma kelo rweny oyoto ki alokaloka me lyeto.

100 mL methanol ki medo (ki gwoko rwom me lyeto

Iyonge dakika 10, ki yubu gin ma ki rubu ni, ki gin ma odong ni ki lwoko ki 50 mL me methanol.

Gin ma ki kwanyo ni tye ki ≥9 g NaHS ki ≤0.6 g Na2CO3 (~3.5 g NaHS ki 0.2 g Na2CO3 pi 100 mL).

Gin ma ki lwongo ni Sodium hydrosulfide ma ki cwalo woko, ngec tye, dii kany me nongo lanyut ma pe ki culu.
