Mmepụta Sodium Hydrosulfide site na Sodium Ethoxide na H2S
Nkwadebe site na Sodium Ethoxide na Hydrogen Sulfide akọrọ
Ntọala Ngwa:
A na-etinye karama 150 mL nke nwere akụkụ aka ya. 20 mL nke a gwakọtara ọhụrụ Ethanol na-anaghị esi mmiri mmiri na 2 g nke iberibe ígwè sodium dị ọcha (enweghị oyi akwa oxide).
A na-etinye ihe na-eme ka a na-akpọ reflux condenser na tube na-akpọ nkụ n'ime karama ahụ, a na-emechikwa akụkụ aka ya ruo nwa oge.
Mgbe sodium ethoxide malitere ịpụta, a na-agbakwunye ihe ọzọ 40 ml nke ethanol na-anaghị agbaze mmiri a na-agbakwụnye ya n'ime akụkụ ruo mgbe ọ ga-agbaze kpamkpam.
Mmeghachi omume na Akọrọ H₂S:
A na-etinye ọkpọkọ iko site n'akụkụ aka n'ime mmiri ahụ, a na-afụkwa gas H₂S kpọrọ nkụ (hụ na ikuku anaghị abanye iji gbochie ikuku ịbanye).
A na-ejupụta mmiri ọgwụ ahụ na H₂S, wee tee ya iji wepụ ihe ọ bụla na-eme ka ọ ghara ịpụta ìhè.
A na-ebufe nzacha ahụ n'ime karama kọnịk akọrọ, ma 50 ml nke ether zuru oke a gbakwunyere, ozugbo NaHS ọcha na-asọpụta.
A na-etinye ether ọzọ (ihe dị ka 110 mL mkpokọta) n'ime akụkụ ruo mgbe mmiri agaghị ezo ọzọ.
A na-asacha ihe na-eme ka mmiri ahụ daa ngwa ngwa, jiri ether saa ya ugboro abụọ ruo atọ, ma kpọọ nkụ n'okpuru ikuku.
Ngwaahịa a dị ọcha nke ukwuu. Maka ịdị ọcha ka mma, enwere ike imegharị ya site na ethanol/ether.
