Carbonate, hydroxide na calcium carbonate

Calcium ... Gịnị ka ị maara banyere ya? "Nke a metal", - dị nnọọ ka zaa ọtụtụ. Na ihe nke calcium ogige adị? Mgbe a na isi na onye ọ bụla ga-amalite na scratching gị isi. Ee, ehighị nne ihe ọmụma banyere oge gara aga, na banyere onwe ya calcium kwa. Na na na, ka okwu banyere ya mgbe e mesịrị, ma n'ihi na ugbu a, ka anya ala atọ na nke ya ogige - carbonate, hydroxide na calcium carbonate.

1. Calcium carbonate

Ọ bụ a nnu nke a kpụrụ site calcium na carbonic acid fọduru. The usoro nke carbonate - CaCO _3.

Njirimara

Ọ nwere n'ụdị a na-acha ọcha ntụ ntụ nke bụ unyi anaghị agbasa na mmiri na ethyl mmanya.

Nkwadebe nke calcium carbonate

Ọ na-kpụrụ n'oge calcination nke calcium oxide. Iji ikpeazụ, mmiri e kwukwara, na mgbe ahụ, mgbe dapụtara ngwọta nke calcium hydroxide a rụrụ carbon dioxide. The mmeghachi omume na ngwaahịa ndị chọrọ carbonate na mmiri, nke na-adị mfe iche na onye ọ bụla ọzọ. Mgbe ọ na-ewe iwe dị ọkụ, ọ ga-cleavage ngwaahịa nke ga-carbon dioxide na quicklime. N'elu mgbasa nke carbonate na carbon monoxide (II) nwere ike na-akwadebe na mmiri nke calcium carbonate. Ọ bụrụ na anyị na ikpokọta carbon na calcium carbonate, ngwaahịa nke mmeghachi omume bụ calcium carbide na carbon monoxide.

Nke a carbonate - nzu bụ na anyị na mgbe nile na-ezute na ụlọ akwụkwọ na ihe ndị ọzọ bụ isi na agụmakwụkwọ ka elu. Ọzọkwa, ha na-tere nzụ n'uko, na-ese ke ini utọ osisi Kporo na mere isi ala hotikoisho ụlọ ọrụ.

2. calcium bicarbonate

Ọ bụ a nnu nke carbonic acid. Nwere usoro Ca (HCO _{3) 2.}

Njirimara

Soluble mmiri, dị ka ihe niile hydrocarbons. Otú ọ dị, ọ bụ n'ihi na ụfọdụ oge na-eme ka o sie ike. Na ndu eme ntule, calcium carbonate na ndị ọzọ na salts, ụfọdụ si na otu radicals nwere ọrụ nke regulators nke mgbe nile na-ọbara Jeremaya mere.

Ọ na-enwetara site omume carbon dioxide, calcium carbonate na mmiri.

Ọ dị n'ime mmiri ọṅụṅụ, ebe ịta ike ịdị iche - si 30 400 mg / l.

3. Calcium hydroxide

Formula - Ca (OH) _2. Nke a na umi bụ a siri ike isi. Dị iche iche na isi mmalite o nwere ike ịbụ na-akpọ slaked wayo ma ọ bụ "efu".

n'ikuku

Ọ na-kpụrụ mgbe akpakanam calcium oxide na mmiri.

Njirimara

O nwere ụdị a na-acha ọcha ntụ ntụ, obere soluble n'ime mmiri. Na-amụba okpomọkụ, ndị ikpeazụ space uru nke solubility mbelata. Ọzọkwa ya nwere ikike neutralize acid kpụrụ n'oge mmeghachi omume kwekọrọ ekwekọ calcium nnu na mmiri. Ọ bụrụ na agbakwunyere ya etisasịwo mmiri, carbon dioxide, na-nwetara niile ahụ mmiri, kamakwa nke calcium carbonate. Na nọgide barbotatsii CO ₂ uche calcium carbonate guzobere.

Ha tere nzụ ụlọ, osisi fences, nakwa dị ka ntekwasa na ntụhie ya. Site a na-akwadebe hydroxide lime ngwa agha, bleach, pụrụ iche fatịlaịza, lime ihe, na ọbụna kpochapụ carbonate ekweghị ekwe nke mmiri (ịrọ arọ ikpeazụ). Site na nke a umi rụrụ causticization potassium na sodium carbonates, akuru mgbọrọgwụ ọwa mmiri nke ezé, ma na-agwọ akpụkpọ tan ụfọdụ osisi ọrịa. calcium hydroxide, makwaara dị ka a nri mmako E526.
