Njirimara na kemịkal nke sodium hydrosulphide (Nahs)
1. Njirimara anụ ahụ
Ọdịdị: sodium hydrosulfide na-abụkarị nke na-acha ọcha ma ọ bụ ọkụ edo edo edo edo edo. O nwekwara ike ịbụ acha odo odo na-acha odo odo, na-enweghị isi kristal nwere isi hydrogen sulfide.
Meld Point: Isi ihe na-agbaze nke sodium na-agbaze bụ 350 Celsius C; Meld na-agbaze nke hydrate dị ala, na 52-54 Celsius C. Agbanyeghị, ụfọdụ data na-egosi na na-agbaze na-agbaze nke sodium hydrosulfide bụ 55 Celsius C.
Ntinye: Ntinye aka nke sodium hydrosulfide bụ 1.79 g / cm³, ma ọ bụ 1790 n'arọ / m.
Solingy: a na-agbanye sodium hydrosulfide na mmanya na mmanya na-egbu egbu, na ihe o mere alkaline. Dabere na ụfọdụ data, ngbanwe nke sodium hydrosulfide na mmiri bụ 620G / l na 20 Celsius C.
2. Akụ kemịkal
Acidity na alkality: Ngwọta osisi nke sodium hydrosulfide bụ alkaline.
Mmeghachi omume na acid: sodium hydrosulfide wepụta gas hydrogen sulfide gas mgbe ọ na-ezute acid. Ntachi obi a bụ: Nahs + H + → H2S ↑ +.
Mmeghachi omume na sulfur: sodium hydrosulfide nwere ike ime ihe na sọlfọ iji mepụta polysilfides, mmeghachi omume bụ: 2NAHS + 4S4.
Mgbanwe: sodium hydrosulfide bụ ebe a na-ejikarị ebe a na-ebelata nke nwere ike itinye mmeghachi omume na ọtụtụ ndị ọxandants.
3. Njirimara ndị ọzọ
Idọbi: sodium hydrosulfide bụ onyinye kwụsiri ike, mana ọ bụ hygroscopic. N'otu oge ahụ, ọ bụkwa ihe siri ike ma nwee ike ịnye ikuku.
Ngabiga na-egbu egbu: Hydrosulfide bụ ihe na-egbu egbu ruo n'ókè ụfọdụ na gburugburu mmadụ. Ya mere, a ga-akwụ ihe pụrụ iche na nchedo nchekwa n'oge ojiji na nchekwa.
