Mhinduro yeSodium Bicarbonate: Nzira yekuenda kuSodium Hydrosulfide
Anhydrous sodium hydrosulfide
Yakagadzirwa sezvakatsanangurwa pamusoro apa pasi pemamiriro akaomarara asina hunyoro.
Mhinduro yeNaHS yemvura
Sodium sulfide nonahydrate (Na₂S·9H₂O) inonyungudutswa mumvura ichangobva kucheneswa kuti iite 13% (w/v) mhinduro yeNa₂S.
Pasi pekukurunga uye pasi 20°C, 14 g NaHCO₃ inowedzerwa ku 100 mL yemushonga uyu, zvichikonzera kunyungudika nekukasika uye kuita kwe exothermic.
100 mL methanol inowedzerwa (ichichengetedza tembiricha iri pasi pe20°C), zvichiita kuti makristaro eNa₂CO₃ awedzere.
Mushure memaminitsi gumi, musanganiswa wacho unosefetwa, uye zvasara zvinosukwa ne50 mL methanol.
Filtrate ine ≥9 g NaHS uye ≤0.6 g Na₂CO₃ (~3.5 g NaHS uye 0.2 g Na₂CO₃ pa 100 mL).
Mutengesi weSodium hydrosulfide brand, ruzivo rwuripo, tinya pano kuti uwane sampuro dzemahara.
