Barium hydroxide. Olee ihe anyị maara banyere ya?

Barium - bụ a chemical mmewere na ndị nke oge table na mkpatụ na mmiri na acid ngwọta. Ọ Nleta barium hydroxide onye usoro bụ Ba (OH) 2 (omenala aha "caustic barite"). Nke a bụ a mgbagwoju inorganic umi. Hibere na o nwere ụdị a na-acha ọcha ntụ ntụ, esịnede uzo kristal. Nke a na umi bụ ukwuu soluble na mmiri - na ọnọdụ okpomọkụ nke mmiri dị elu, mma solubility. "Barite mmiri" (ma ọ bụ a jupụta barium hydroxide ngwọta) kwuru na mmiri nke na-etisasịwo Ba (OH) 2. Barium hydroxide kpamkpam mkpatụ na carbon dioxide, ya mere ya okenye ihe ngwọta (ma ọ bụ "barite mmiri") na-eji na gbasara nyocha onwu dị ka a reagent maka CO2.

Ọzọkwa, barite mmiri nwere ike ije ozi dị ka a reagent ka sulfate na carbonate ion. Na ezi mmiri solubility nke barium hydroxide bụ kpam kpam unyi anaghị agbasa na-aba n'anya. Nke a na atụmatụ na ọtụtụ-eji dị iche iche na ndi nke aku na uba. Ma tupu iji hydroxide, mkpa ka ị na-amụta banyere otú ọ na-emepụta si dị reagents. N'ihi ya, barium hydroxide na-enwetara site dissolving na mmiri ọkụ ma ọ bụ site na kpo oku oxide nke barium sulfide na a iyi nke dị oké ọkụ uzuoku. Nke a nwere ike nweta naanị na laabu, dị ka ná ndụ kwa ụbọchị, nke a ọ bụghị nanị agaghị ekwe omume, ma na-ize ndụ nke ụmụ mmadụ na ahụ ike.

Barium hydroxide na-eji maka na mwepụ nke sulfate ion si anụ na akwukwo nri mmanụ, ụlọ ọrụ mmepụta ihe ngwọta, nakwa dị ka eji na-akwadebe cesium na rubidium hydroxide ka a mmanu akụrụngwa.

Barium hydroxide nwere dị iche iche Njirimara, gụnyere alkali. Ọ na-eji na mmanụ ụlọ ọrụ site na-eme ka mmanụ nwekwara. Ọzọkwa, ndị dị otú ahụ a hydroxide n'ụzọ zuru okè na-egosipụta onwe ya dị ka ihe mmako na mmanụ, ya mere, ugbu a ọ dabeere na-amị a nọmba nke yiri ngwaahịa. Non-ferrous nkà mmụta banyere ígwè na chemical ụlọ ọrụ ojiji nke barium hydroxide na ha ọrụ. Ọtụtụ-eji dị ka barium oxide hydrate reagent ka SO42- na CO32-, n'oge ihicha nke anụmanụ abụba na akwukwo nri mmanụ dị ka mmanu akụrụngwa, mgbe wepụ SO42- si ulo oru ngwọta.

Nkwadebe nke Ba salts na hydroxides, CS, Rb nke ha sulfates ma ọ bụ carbonates bụ na-enweghị iji dị otú ahụ reagent ka barium hydroxide. Nke a na atụmatụ nke na-aghọkwa ndị bụ isi na-ekpebi ihe ndị pụrụ iji nke hydroxide na njem. N'ụzọ dị ịtụnanya, barium na-eji ike aka wuru komeeti: a ụzọ barium, nke na-wepụtara na osisi ugboelu, agbasaghị ngwa ngwa ionize anyanwụ na ụzarị ma ghọọ a na-egbuke egbuke plasma ígwé ojii.

Na iri-na-iteghete nke ikpeazụ narị afọ iri, mgbe Soviet interplanetary akpaka ọdụ "Luna-1" na-eme ya elu, mbụ wuru komeeti e kere. Physics America na Germany na seventies, ịgagharị akpa ubi nke Earth, mere ntọhapụ nke barium powder na ego nke iri na ise kilogram dị n'elu Colombia. Nke a rụpụtara na a plasma ígwé ojii, nke nwere elongated udi, emi odude tinyere ndọta, na-eme ka o kwe omume-ezipụta ha na ọnọdụ. Iri afọ abụọ mgbe e mesịrị, ndị ahụ nke barium sulfate na barium ghọrọ ka jets na-eji na-amụ ihe Aurora.

Dị ka ị pụrụ ịhụ site na niile dị n'elu, barium hydroxide bụ nnọọ ihe dị mkpa akụrụngwa na oge a na ụlọ ọrụ. Enweghị ya pụrụ iche Njirimara ga-abụ nnọọ ihe siri ike na-ebu ụfọdụ ọrụ. Anyị na-enweghị ike ịnabata na kere mgbe iji hydroxide reagents na-ọtụtụ-eji ihe fọrọ nke nta nile ndi nke aku na uba!
