Litaba

1. Mokhoa oa ho amohela:
Absorb hydrogen SULFIDE SOLFIDE SOLFIDE le tharollo ea sulfide (kapa tharollo ea soda). Hobane khase ea Shulfide ea hydrogen e na le chefo, karabelo ea monyako e lokela ho etsoa tlasa khatello e mpe. Bakeng sa ho thibela tšilafalo e phahameng ea moea ka hydrogen fulfide ea ho khatholla ha motlakase ka har'a tlhahiso, 'me litaba tsa sydrogen sulfide li fokotsehile ka tlase ho moo. Mokelikeli oa monyako o shebane le ho fumana sodium hydrofulfilloe. Foromo ea eona ea lik'hemik'hale:
H2s + Nao → Nahs + h2o
H2s + na2s → 2nahs

2. Sodium Alkoxide Recfide e omileng ea hydrogen o omileng ho Lokisa Sodium hydrosulfide:
Ka bo-'makhali ba 150ml le pipi ea lekala, eketsa lekhali le sa thabiseng le 2G ea likheo tsa tšepe, kenya khomphutha e omileng, 'me u koale popi Ha sokoxide a hloekile, eketsa hoo e ka bang 40 ml ea ethanol e fetang ka litlamo ho fihlela sodium alkoxide e qhibiliha ka botlalo.
Kenya thajana ea khalase ka tlase ho tharollo ea pope, 'me u fetise khase e omileng ea haedrogen (hlokomela hore ha ho na moea oa lekala. Lutlarate tharollo. Tharollo e ne e suna e hapiloeng hore e tlose ho otlolla pula. Filtraraterate e bolokiloe ka har'a Flask e omileng, le 50 ml ea Eles e phethahetseng, 'me boholo ba sebaka se seholo sa Nahs White o ile a hahuoa hang-hang. Kakaretso ea hoo e ka bang 110 ml ea ether ea ether. Pōpo e ne e boetse e hloeloa kapele, e hlatsoitse makhetlo a 2-3 ka ehete, o omiloe o omiloe, 'me a beha Desiccator ea koluoa. Ho hloeka ha sehlahisoa se ka fihla ho hloeka ha motho. Haeba bohloeki bo phahameng bo hlokahala, e ka qhibiliha ka ethanol mme e nchafalitsoe ka ether.

Metsi a 3.sodoim hydrosulfide:
Dissolve Sulfide Soulfide Soulfide Foreide Metsi a Sehlōhō Tse Hlakiloeng Metsi a Sehjung, ebe o hlasimolla tharollo ea li-13% Na2s (W / v) Tharollo. 14 g ea sodium bicarbonate e ile ea eketsoa tharollong e kaholimo (100 ml) ka ho hlohlelletsa le tlase ho 20 ° C, ho sa feleng le ho ba teng. Ka mor'a moo 100 ml ea methanol e ile ea eketsoa ka tšusumetso le ka tlase ho 20 ° C. Hona joale bothata bo ile ba etsa hore motho e mong le e mong a be le kristamone sodium carbonate. Kamora metsotso e 0, motsoako o ne o hloekisoa ka ho chesoa le masala a hlatsuoa ka methanol (50 ml) ka likarolo tse 50. Sekhahla se se nang tlase ho 9 g of sodium hydrolelofide mme ha a feta liperesente tse 0,6 tsa sodium carbonate. Mehopolo ea bobeli e ka ba ka bang 4,2 le ligrama tse 0,2 ho isa ho 100 ml ea tharollo, ka tatellano.

Re tloaetse ho e lokisa ka ho monya hydrogen Sumfide Contharide le tharollo ea sodium hydroxide. Ha litaba (karolo e ngata ea sodium hydrosulfide) ke 70%, ke khetho e fapaneng ebile e ka mokhoa oa lipalesa; Haeba litaba li tlaase, ke sehlahisoa se metsi, ke hydrate e merara.
