1. Boric acid wani fili ne na crystalline da aka samar ta hanyar narkar da boron trioxide a cikin ruwa.Yana da inorganic acid, yafi ciki har da tetraboric acid H2B4O7 (kuma aka sani da pyroboric acid), metaboric acid (HBO2) n da kuma orthoboric acid H3BO3 (wanda aka sani da orthoboric acid).Daga cikin su, orthoboric acid yana da mafi kwanciyar hankali abun ciki na ruwa.Orthoboric acid, wanda kuma ake kira boric acid a takaice, fari ne kristal foda ko triaxial chemicalbook scaly junction crystal tare da luster.Yana da ɗanɗano mai ɗaci.Yana jin maiko a hulɗa da fata.Ba shi da wari kuma mai narkewa a cikin ruwa, ethanol, glycerin, ethers da jigon.Maganin ruwa yana da rauni acidic.Orthoboric acid yana raguwa a hankali zuwa metaboric acid lokacin zafi zuwa 70-100 ℃, pyroboric acid lokacin mai tsanani zuwa 150 ℃ -160 ℃, da kuma boric anhydride (B2O3) lokacin zafi zuwa 300 ℃.
2. Maganin ruwa yana da rauni acidic, wanda shine al'ada Lewis acid.A gaban hydrochloric acid, citric acid ko tartaric acid, zai iya inganta solubility a cikin ruwa.Saboda haka, ana iya tsarkake ta ta hanyar recrystallization.
3. Gabaɗaya, boric acid ba mai guba bane.Matsakaicin kisa na manya yana kusan gram 15 ~ 20 a kowace kilogiram na nauyin jiki, yayin da na yara ya kai gram 3 ~ 6 a kowace kilogiram na nauyin jiki.Yawan sha na iya haifar da guba mai tsanani.Alamomin farko sune amai, gudawa, kurjin fata, kuma tsarin juyayi na tsakiya yana farin ciki da farko sannan kuma ya hana.Mummunan gazawar jini ko girgiza, yawanci a cikin kwanaki 3 zuwa 5 na mutuwa.Maimaita shan kananan allurai zai taru a cikin jiki, wanda zai haifar da guba na yau da kullun, anorexia, gajiya, hauka, dermatitis, gashin gashi, da rikicewar al'ada.
