Taw qhia thiab khoom
Taw qhia
Boric acid tseem hu ua "orthoboric acid". Nws yog muab los ntawm kev sib cuam tshuam ntawm ntuj borax (sodium borate) thiab acid. Cov tshuaj formula H3BO3. Molecular hnyav 61.83. Dawb triclinic nplai nrog glossy crystals. Tus txheeb ze ntom ntom yog 1.43514, thiab qhov ntsuas qhov taw qhia yog 1.337, 1.461, thiab 1.462. Soluble hauv dej, ethanol Chemicalbook thiab glycerol. Cov tshuaj aqueous yog acidic thiab yog monovalent tsis muaj zog acid (Ka = 6 × 10-10). Solubility hauv dej nce nrog kub. Ua kom sov rau 169 ℃ (± 1 ℃), lub cev qhuav dej yuav tsim cov tshuaj metaboric acid, thiab 300 ℃ yuav tsim boric anhydride. Neutralize nrog muaj zog alkali kom tau metaborate. Tetraborate tau txais nyob rau hauv tsis muaj zog alkaline tej yam kev mob.
Khoom
Txoj kev npaj: Hydrochloric acid los yog sulfuric acid tuaj yeem muab ntxiv rau cov tshuaj borax, los yog nws tuaj yeem tau los ntawm decomposing boraxite nrog hydrochloric acid. Kev Siv: Siv dav hauv kev tsim cov borate, dej iav, borate ester, kho qhov muag tshuaj iav, enamel, xim, xim, tshuaj pleev ib ce, zaub mov preservatives, tawv xov, luam ntawv thiab dyeing auxiliaries thiab tshuaj, thiab lwm yam. Nws kuj yuav siv tau raws li antiseptic. tshuaj tua kab mob, astringent.
