Mmepụta Sodium Hydrosulfide site na Ntinye NaOH
Usoro Mmịpụta NaOH nkịtị
Mgbe njupụta nke sodium hydrosulfide NaHS ruru Pasentị iri asaa, ọ na-emepụta ntụpọ dihydrate.
Na obere nchịkọta, ọ dị ka mmiri mmiri trihydrate.
Usoro:
A na-etinye karama gbara okirikiri nke nwere olu atọ nke otu lita, ihe na-akpali akpali na ihe na-eme ka mmiri ghara ịdị ọcha (ejikọrọ na tube nkụ CaCl₂).
A na-eji nitrogen akọrọ sachaa karama ahụ, wee tinye ya n'ọkụ. 200 mL (3.4 mol) ethanol na-anaghị agbaze mmiri.
A na-etinye 12 g (0.522 mol) nke sodium metal dị ọcha n'ime obere iberibe tupu a na-akpali ya ma na-emegharị ya ruo mgbe ọ ga-agbaze kpamkpam.
A na-etinye ọkpọkọ gas n'ime mmiri mmiri ahụ, a na-etinyekwa H₂S kpọrọ nkụ (a kpọrọ nkụ karịa P₂O₅) n'ime afụ 5–10/sekọnd ruo awa abụọ ka a na-agwakọta ya.
Mgbe ọ jụrụ oyi, a na-etinye 750 mL nke ihe na-anaghị agbaze mmiri iji mee ka NaHS sodium hydrosulfide gbapụta kpamkpam.
Ọrụ:
A na-asacha ngwakọta ahụ ngwa ngwa (mkpụcha akpụkpọ ahụ) iji gbochie mmiri ịmịkọrọ.
A na-asa ihe siri ike ahụ site na iji ether na-anaghị agbaze agbaze 3×, wee kpọọ ya nkụ n'ime ihe na-ekpo ọkụ ikuku (CaCl₂) ruo ọtụtụ awa.
Mmepụta: 29.4 g nke ≥98% NaHS dị ọcha.
