Nhanganyaya
Boric acid inonziwo "orthoboric acid". Inotorwa kubva mukubatana pakati pechisikigo borax (sodium borate) uye asidi. Mushonga wemakemikari H3BO3. Molecular uremu 61.83. Zviyero zvichena zvetriclinic zvine makristasi anopenya. Kuwanda kwehukama ndeye 1.43514, uye refractive index ndeye 1.337, 1.461, uye 1.462. Soluble mumvura, ethanol Chemicalbook uye glycerol. The aqueous solution is acidic and is a monovalent weak acid (Ka=6×10-10). Solubility mumvura inowedzera nekupisa. Kupisa kusvika 169 ℃ (±1 ℃), kupera mvura mumuviri kunoburitsa metaboric acid, uye 300 ℃ ichagadzira boric anhydride. Neutralize nealkali yakasimba kuti uwane metaborate. Tetraborate inowanikwa pasi pemamiriro asina kusimba alkaline.
Property
Nzira yekugadzirira: Hydrochloric acid kana sulfuric acid inogona kuwedzerwa kumushonga weborax, kana inogona kuwanikwa nekuora boraxite nehydrochloric acid. Kushandiswa: Inoshandiswa zvakanyanya mukugadzirwa kweborate, girazi remvura, borate ester, optical chemical glass, enamel, pendi, pigment, cosmetics, zvokudya zvinochengetedza, kupedzisa kweganda, kudhinda uye kudhaya zvinhu zvinobatsira uye mishonga, nezvimwewo. Inogonawo kushandiswa seantiseptic. mushonga unouraya utachiona, unorwadza.
Mazano
Mhoro, ndafara kusangana newe pano. Unofarira chigadzirwa ichi? Ichi chigadzirwa chinoiswa pamasherufu neni. Ndinoziva zvakawanda nezvechigadzirwa ichi. Kana iwe uchida chero kubvunzurudzwa, unogona kundibata chero nguva uye edza kukupa iyo inogutsa kwazvo pre-kutengesa uye mushure mekutengesa masevhisi. Ruzivo rwangu rwekufonera rwuri pazasi, gamuchirai kubvunza kwenyu.
