Nkatsakanyo wa Sodium Bicarbonate: Ndlela yo ya eka Sodium Hydrosulfide

Leswi nga riki na mati sodiyamu ya hayidirosulfayidi

Yi lulamisiwa tani hileswi swinga hlamuseriwa laha henhla ehansi ka swiyimo swo tika leswinga riki na ndzhongho.

Xitshunxo xa NaHS xa Mati

Sodium Sulfide ya xirhendzevutani nonahydrate (Na2S·9H2O) yi pfanganisiwa na mati lawa ya ha ku khukhuriwaka ku endla a13% (w/v) Xitofu xa Na2S.

Ehansi ka ku hlanganisiwa na le hansi 20°C, . 14 g ya NaHCO3 ku engeteriwa eka 100 mL ya xirhendzevutani ya solution leyi, leswi vangaka ku khuluka ka xihatla na exothermic reaction.

Kutani ku cheriwa 100 mL ya methanol (ku hlayisa mahiselo

Endzhaku ka 10 min, nkatsakanyo wu sefiwile, naswona masalela ya hlantswiwa hi 50 mL ya methanol.

Filtrate yina ≥9 g NaHS na ≤0.6 g Na2CO3 (~3.5 g NaHS na 0.2 g Na2CO3 hi 100 mL).

Muxavisi wa brand ya Sodium hydrosulfide, data ya kumeka, tinya laha ku kuma swikombiso swa mahala.
