Samar da Sodium Hydrosulfide ta hanyar Sodium Ethoxide da H2S
Shiri ta hanyar Sodium Ethoxide da Busasshen Hydrogen Sulfide
Saitin Na'ura:
Ana cajin kwalbar 150 mL tare da gefen hannu 20 ml na sabon tarkacen Ethanol mai ruwa kuma 2 g na sassan ƙarfe masu tsabta na sodium (ba tare da yadudduka na oxide ba).
An sanya kwalbar da na'urar sanyaya iska da bututun busarwa, kuma an rufe gefen gefen na ɗan lokaci.
Bayan sodium ethoxide ya fara samuwa, ƙarin 40 ml na ethanol mai ruwa-ruwa ana ƙara shi a cikin rabo har sai ya narke gaba ɗaya.
Amsawa da Dry H₂S:
Ana saka bututun gilashi ta gefen hannun a cikin ruwan, sannan a zuba iskar H₂S busasshiya (a tabbatar da cewa iska ba ta shiga don hana iska shiga).
Ana cika maganin da H₂S, sannan a tace shi don cire duk wani abu da ya fashe.
Ana canja wurin tacewa zuwa busasshen kwalbar mazugi, kuma 50 ml na cikakken ether an ƙara, nan da nan farin NaHS ya ratsa.
Ana ƙara ƙarin ether (~110 mL jimilla) a cikin rabo har sai babu wani ƙarin ruwan sama da zai sake faruwa.
Ana tace ruwan da ke cikinsa da sauri, a wanke shi sau 2-3 da ether mai kyau, sannan a busar da shi a ƙarƙashin injin tsabtace iska.
Samfurin yana da tsarkin nazari. Domin samun tsarki mai kyau, ana iya sake yin amfani da ethanol/ether.
