OXALIC ACID
Oxalic acid yog crystalline khoom ntawm chav tsev kub thiab tsis muaj xim. Nws yog heev soluble nyob rau hauv dej, tsim ib tug ntshiab, tsis muaj xim tov. Lub solubility hauv lwm cov kuab tshuaj xws li ethanol yog qis dua. Nws muaj qhov melting point ntawm 101-102 degree thiab decomposes ua ntej boiling. Nws yog ib qho muaj zog acid nyob rau hauv cov kua dej aqueous, muaj peev xwm pub ob lub protons ib molecule. Cov kua qaub dissociation tas li (pKa) qhov tseem ceeb rau nws ob theem dissociation yog kwv yees li 1.27 thiab 4.27. Nws yog ib qho tseem ceeb rau nws lub peev xwm los tsim cov complexes ruaj khov nrog hlau ions, vim nws cov bidentate chelating zog. Cov khoom no ua rau oxalic acid pab tau ntau yam kev siv hauv kev lag luam, xws li hauv cov txheej txheem bleaching, ua tus neeg saib xyuas, thiab hauv kev sib txuas ntawm cov tshuaj thiab tshuaj.

Oxalic acid pom nws siv dav hauv cov txheej txheem kho dej vim nws cov khoom tshwj xeeb. Nws yog feem ntau siv los ua tus neeg sawv cev chelate los khi nrog cov hlau ions xws li calcium thiab hlau, yog li tiv thaiv kev tsim cov nplai hauv cov kav dej thiab cov khoom siv. Ntxiv nrog rau nws lub luag haujlwm hauv kev tiv thaiv scaling, nws muaj txiaj ntsig zoo hauv kev tshem tawm cov xeb thiab cov pob zeb hauv av los ntawm qhov chaw los ntawm nws cov kua qaub. Nws lub peev xwm los tsim cov txheej txheem soluble nrog cov hlau ua rau nws muaj txiaj ntsig zoo hauv kev tu thiab tu cov txheej txheem, ua kom muaj kev ua haujlwm zoo ntawm cov tshuab dej thiab ua kom lub neej ntev ntawm cov khoom siv. Nws yog versatility nyob rau hauv kev kho dej underscores nws tseem ceeb nyob rau hauv kev tswj dej zoo thiab kev ua hauj lwm efficiency nyob rau hauv ntau yam lag luam.
