Uas muaj peev xwm ntawm Mohr lub ntsev

Mus taug kev nyob rau hauv lub tiaj ua si lub hnub, kuv tau pom kuv tus qub phooj ywg. Pub ntxiv tshaj lub tuam txhab unwittingly coj ib feem nyob rau hauv lawv yav tas los launched rau kev sib tham. Cov kev kawm tsis muaj lub feem ntau paub - uas tsis yog-humanitarian profile. Tab sis kuv xav nyob rau hauv thiab involuntarily mloog, ua kom to taub cov kev sib tham. Heev npaum li cas tej yam txaus siab cov phooj ywg sib noog sib. Lawv tham txog ib co mas tshuaj. Kuv nyiam ib tug txiv neej, ua luaj deb ntawm science, xav tias tus hais lus yuam kev, siv ib tug coj txawv txawv lub npe - "Mohr lub ntsev." Tej zaum nws cia li misspoke los yog kuv misheard nws tus kheej. Thaj, peb yuav sib tham txog lub hiav txwv ntsev, tab sis nyob rau hauv no lub ntsiab lus kuv nyuam qhuav pom kuv tus hluas nkauj rov qab los ntawm tours nyob rau hauv cov Yixayee.

Muaj yog ib tug zoo so rau ntawm ntug dej ntawm lub tuag hiav txwv, thiab tau tam sim no ua ib tug kub siab lug activist siv tshuaj pleev ib ce raws li nyob rau hauv marine cov zaub mov thiab ntsev. Tsis tas li ntawd coj ib tug loj hub zaub mov nrog cov hiav txwv ntsev los ntawm lub dawm. Nws nce kuv qhov haum ntawm cov zaub mov yog xws li ib tug ntsev, enriched nrog iodine thiab lw ntsiab.

Intrigued, kuv nug dua, seb puas nyob rau hauv lub siab lub ntsev ntawm lub tuag hiav txwv. Tab sis, nws muab tawm, cov thawj lub sij hawm kuv hnov kom raug. Lub ntsiab lus ntawm kev sib tham tsis yog lub hiav txwv. Hais yog, tseeb, Mohr lub ntsev. Kuv tau piav hais tias qhov no tshuaj inorganic keeb kwm, muaj rau hauv daim ntawv ntawm muaju ntawm daj ntseg ntsuab xim. Kuv mam li bet lawv tsis xav hais tias kuv yuav nco ntsoov hais tias thaum hu ua Mohr lub ntsev "crystalline hydrate ob ammonium sulphate ntawm hlau." Vim hais tias lub clarified tias cov tshuaj yeeb dej caw yog tsis xa mus rau raws li ib tug muab ob npaug rau sulfate ammonium ntsev , thiab ferrous oxide.

Luv Npe - Mohr ntsev (formula FeSO 4 × (NH 4) 2 li 4 × 6H 2 O thiab chaw pom tau hais tias lub npe «Mohr lub ntsev» Kuv twb podsmotreny lub Internet nyob rau hauv rau yav tsaus ntuj). Main Cheebtsam: hlau, sulfur, oxygen, hydrogen, nitrogen. Nyob rau hauv mikrodolyah intrusion ntawm impurities (tshuaj, manganese, tooj liab, hlau thiab ib co lwm tus neeg).

Cov tshuaj yeeb dej caw uas muaj peev xwm yaj nyob rau hauv dej thiab acids (feem ntau). Cov nruab nrab yog huab cua ruaj khov compound. Daim ntawv thov no nyob rau hauv ntau industries. Piv txwv li, nyob rau hauv Science News for KIDS - rau kev tsom xam cov concentration ntawm cov tshuaj yeeb dej caw nyob rau hauv cov tshuaj (poov tshuaj permanganate - los mus txiav txim titer, thaum txiav txim ntawm lub ntim ntawm vanadium, chromium, ether thiab ethyl cawv). Cov ntsev muaj lawm hos tseem nyob rau hauv cov ntoo - mas concentrated tshuaj ntawm nws siv rau lub impregnation ntawm ntoo los mus tiv thaiv putrefaction.

Thaum lub sij hawm qhov kev sib tham lawv kov raws li qhov kev siv ntawm Mohr lub ntsev nyob rau hauv pharmacology thiab tshuaj. Nws yuav siv tau raws li ib tug khoom noj khoom haus additive, thiab kuj siv rau nce tus naj npawb ntawm cov ntshav, ua rau cov theem ntawm hemoglobin nyob rau hauv cov ntshav. Siv nws kuj yuav qhia tau urobilin nyob rau hauv cov zis - ib yam khoom uas indicative ntawm lub raum teeb meem. Lub usefulness ntawm no ntsev yog vim muaj ib tug tseem ceeb cov ntsiab lus ntawm cov hlau oxide uas yuav tau yooj yim yuav absorbed los ntawm tib neeg lub cev.

Nws xav tias nws yog funny tias rau lub thib ob lub sij hawm nyob rau hauv ib lub lim tiam, cov neeg sib txawv qhia rau kuv txog cov kev pab cuam ntawm ib tug txawv txawv ntsev. Thaj, nws yog ib tug kos npe rau tias peb yuav tsum tau them ntau xim rau lawv noj qab haus huv thiab pib noj tsis yog rooj ntsev, tab sis ib yam dab tsi pab tau ntau. Mora yog tsis - qhov no tsis tas li ntawd tej zaum yuav appoint ib tug kws kho mob, tab sis yam tsawg kawg yog iodized txav rau yog tias cov Yixayee yuav tsis tau txais. Los sis tej zaum txawm Kis mineral ntsev los ntawm cov tuag hiav txwv mus coj ib tug da dej nrog nws, ntxias kom zoo siab tus qab haus huv.
