Barium hydroxide. He aha e mākou i ike ai ia ia?

Barium - mea he Nine Inch hehee ai i loko o ka papa'āweʻaweʻa kemika papaʻaina e reacts me ka wai a me kaʻakika pāʻoihana. Ua 'ano apau loa barium hydroxide nona ka haʻilula o BA (OH) 2 (kuʻuna inoa "caustic barite"). Kēia mea he luna ''okanikaʻole waiwai. Externally ka mea, i ke ano o ke keʻokeʻo he lepo lā, iloko olaila ka aniani moakaka nā pōaka. Kēia waiwai i loa wailana i loko o ka wai - a me ka wela o ka wai o luna, me ka maikaʻi solubility. "Barite wai" (a me ka paʻa kūhohonu loa barium hydroxide pāʻoihana) haawiia i ka wai i loko o i ua mea hoʻoheheʻe BA (OH) 2. Barium hydroxide me ke alalai ole reacts me ke kalapona'okikene lua, a ua hoʻohana 'ia no ia mea, kona koʻana koko pāʻoihana (a "barite wai") ma ka mākau kemika like me ka mea kemikala no CO2.

Eia kekahi, barite wai hiki ke malama i ka mea kemikala e sulufahate a kalepona Ion. Me ka maikai i ka wai solubility o ka barium hydroxide mea pono insoluble ma ka waiʻona. Kēia hiʻona ua hoʻomano hoʻohana 'ia i loko o kekahi mau nāʻoihana o ka hoʻokele waiwai. Akā, ma mua ka hoʻohana 'ana i ka hydroxide, e pono e aʻo e pili ana pehea ka mea, ua hua mai la ia mai loaʻa reagents. Pela, ke barium hydroxide ua loaa ia ma ka mea hoʻoheheʻeʻia i loko o ka wai wela ole ma ka paio hahana maoli nō'okesaside o ka barium sulfide i loko o ke kahawai o superheated mahu. Ua hiki ke loaʻa wale nō i loko o ke keʻena hoʻokolohua, e like me ka maʻamau o ke ola, i kēia kaʻina mea ole wale ole, akā, i pilikia no kanaka ola.

Barium hydroxide ua hoʻohana 'ia no ka wehe' ana i sulufahate Ion mai ka holoholona a me kaʻai mea kāhinu, hanalima pāʻoihana, e like me ia, e hoomakaukau i ka cesium a me ka rubidium hydroxide like me ka lubricant ke keʻena.

Barium hydroxide he waiwai, me mekala 'åkilikai. Ua Ua hoʻohana 'ia i loko o ka aila ma ka hana ana i kaʻaila mea hoʻonui. Eia hoʻi, e like me ka hydroxide wahi aku me ka hoike mai ai ia ia iho, e like me ka mea hoʻonui i kaʻaila, no laila, e ka mea, ua nānā 'ana ma luna o ka hana i ka helu o ka like huahana. Ole-ferrous metallurgy a me ka Nine Inch oihana lawelawe o ka barium hydroxide i loko o kā lākou mau hana. Hoʻomano hoʻohana like me ka barium'okesaside hydrate mea kemikala e SO42- a me CO32-, i ka hoʻomaʻemaʻeʻana o ka holoholona i ka momona, a me nā'ōpū i mea kāhinu, me lubricant ke keʻena, ka wā wehe SO42- mai hanalima pāʻoihana.

Makaukau o ka BA paʻakai a me hydroxides, cs, Rb o ko lākou mau sulfates paha carbonates mea,ʻaʻole me ka hoʻohana 'ana i ka mea kemikala like barium hydroxide. Kēia hiʻona ua lilo no hoi lakou apau i ka hoomaopopo ana i ka Loaʻaʻia ana o ka hydroxide i loko o ka hana. Surprisingly, barium ua hoʻohana 'ia no ka ho okumu ana iʻimi hoʻopunipuni comet: he mau o ka barium, a i kuu ma luna o ka spacecraft, kamaʻilioʻana, e hooholo koke ionize i ka la ka kukuna a huli i loko o ke ao alohilohi i wai koko ao.

Ma he kanalima-iwa o ka makahiki o ka hope Ka Wā Kaukani, i ka wa a ka Soviet interplanetary akomi ia hoonoho ai i "Luna-1"ʻo ia kona holo, ua hanaia ka mea muaʻimi hoʻopunipuni comet. Ke kālaikūlohea Amerika a me Kelemania, i loko o nā seventies,ʻimi ana i ka electromagnetic a mahinaʻai o ka Honua, i ke kala o ka barium pauka i loko o ka nui o ka umikumamalima kilograms pono ma luna Colombia. He kūpono i loko o ka wai koko ao, a i ka elongated kinona, ua aia ma kaʻume mākenēki kula, e ka mea hiki ke hoakaka i ko lakou wahi. He iwakālua nā makahiki ma hope, i hoʻohana 'ia i nā (particles) o barium sulufahate a me ka barium hoohuliia i jets ma ka hoʻopaʻa' ana o ka holaKahua.

E like me 'oe ke ike mai a pau o ka luna, barium hydroxide mea hala loa he nui ke keʻena i loko o kēia hana. Me kona kūlana waiwai e e kokoke paʻakikī e lawe mai i kekahi mau hana. Mākou i hiki oleʻae i ka hana ia ka hoʻohana 'ana i ka hydroxide reagents e hoʻomano hoʻohana i aneane a pau nāʻoihana a pau o ka hoʻokele waiwai!
