Oxalic acid (C₂H₂O₄) lurks nyob rau hauv spinach, rhubarb nplooj, thiab tsaus qhob noom xim kasfes -txoj kev tshuaj tua kab, tshuaj lom txaus tua ib tug yaj grazing tsis tau maj txaus los kho cov ntoo qhib antique. Cov koob tshuaj no ua rau cov tshuaj lom, thiab qhov no dicarboxylic acid taug txoj kab kev phem.

Xyoo 2013, New Zealand beekeepers tau saib ntau txhiab tus khaus khaus. Varroa mites tau tsim kev tiv thaiv rau hluavtaws acaricides. Kev poob siab, apiarists vaporized oxalic acid crystals hauv cov cheeb tsam thaum lub caij ntuj no tsis muaj broodless. Cov kua qaub sublimates, txheej muv thiab mites zoo ib yam; kev tu tus cwj pwm kis nws los ntawm pawg. Mite tuag ntaus 95%. Cov zib ntab tseem tshuav -dawb-oxalic acid decomposes rau CO₂ thiab dej, tsis muaj tshuaj lom nyob rau hauv lub Hive. Niaj hnub no nws yog lub caj qaum ntawm cov organic beekeeping thoob ntiaj teb, tsis tau tib yam compound nyob rau hauv rhubarb nplooj yuav pw tsev kho mob tus me nyuam uas yuam kev rau lawv rau celery.
Woodworker's Secret
Blackwater extract los ntawm tannin-nplua nuj oak reacts nrog hlau los ua dab tuag grey stains. Furniture restorers txhuam oxalic acid tov, tos kaum feeb, yaug. Cov hlau -oxalate complex dissolves; ntoo bleaches rau thawj zib mu tones. Tsis muaj sanding, tsis muaj stripping. Victorian marquetry, dej-kev puas tsuaj parquet, xyoo pua- qub gunstocks-txhua yam cawm tau los ntawm ib lub tebchaw uas kuj tshwm sim rau lub raum pob zeb khoom.
Lub raum pob zeb txuas
Tib neeg metabolize oxalate tsis zoo. Spinach smoothies xa txaus kom crystallize nrog calcium nyob rau hauv lub raum tubules, ua rau lub raum pob zeb ntau tshaj plaws. Txawm li cas los xij, lub cev kuj tseem tsim cov oxalate los ntawm vitamin C overdose thiab ethylene glycol lom. Cov chav xwm txheej kub ceev tswj cov calcium chloride kom precipitate insoluble calcium oxalate ua ntej nws mus txog rau ob lub raum -ib haiv neeg tawm tsam tib chemistry uas ntxuav koj lub lawj.
Muaj Precision
Lub ntiaj teb tsis tshua muaj kev ua haujlwm cia siab rau oxalic acid los ua kom cov lanthanides los ntawm cov kua qaub mine. Txhua lub ntsiab lus tsim oxalate ntawm subtly sib txawv solubilities, ua kom sib cais ntawm neodymium rau hlau nplaum, europium rau phosphors. Koj lub smartphone lub vibration lub cev muaj zog? Tej zaum muaj neodymium purified los ntawm nplooj tshuaj lom no.
Kev Txiav Txim
Oxalic acid yog biochemistry ob tus neeg sawv cev: qhov tseem ceeb metabolic byproduct, muaj zog toxin, maj mam restorer, thiab industrial separator. Nws dissolves xeb, bleaches ntoo, tua mites, thiab qee zaus thaiv tib neeg ureters. Cov ntsiab lus yog txhua yam; lub molecule tsuas yog reacts.
