Maganin Sodium Bicarbonate: Hanya zuwa Sodium Hydrosulfide
Ruwan da ba ya da ruwa sodium hydrosulfide
An shirya kamar yadda aka bayyana a sama a ƙarƙashin yanayi mai tsauri wanda ba shi da danshi.
Maganin NaHS na Ruwa
Ana narkar da sinadarin sodium sulfide nonahydrate (Na₂S·9H₂O) a cikin ruwan da aka tace sabo don yin Maganin Na₂S 13% (w/v).
A ƙarƙashin juyawa da ƙasa 20°C, 14 g NaHCO₃ an ƙara shi 100 ml na wannan maganin, yana haifar da narkewa nan take da kuma amsawar exothermic.
Sannan a ƙara methanol 100 mL (a kiyaye zafin jiki ƙasa da 20°C), yana ƙara ruwan lu'ulu'u na Na₂CO₃.
Bayan minti 10, sai a tace hadin, sannan a wanke ragowar da 50 mL methanol.
Tacewar ta ƙunshi ≥9 g NaHS da ≤0.6 g Na₂CO₃ (~3.5 g NaHS da 0.2 g Na₂CO₃ a kowace 100 mL).
Mai fitar da alamar sodium hydrosulfide, bayanai suna nan, danna nan don samun samfura kyauta.
