mokhoa oa ho etsa hydrogen chloride
1. Ho lokisa HCl joang ka laboratoring?
Ho na le mekhoa e 'meli e tloaelehileng ea ho lokisa HCl ka laboratoring:
Chlorine e kopana le hydrogen:
Cl2 + H2 → 2HCl
Hydrochloride e arabela ka li-acid tse matla:
NaCl + H2SO4 → HCl + NaHSO4
Ammonium chloride e arabela ka sodium hydroxide:
NH4Cl + NaOH → NaCl + NH3 + H2O
2. Hydrogen chloride e hlahisoa hokae?
Hydrogen chloride e teng tlholehong libakeng tse joalo ka ho foqoha ha seretse se chesang, mouoane oa metsi a leoatle, le liphoso tsa litšisinyeho tsa lefatše. Ka indasteri, hydrogen chloride e hlahisoa haholo ke ts'ebetso ea chlor-alkali.
3. Ke hobane'ng ha HCl e le asiti e matla ka ho fetisisa?
HCl ke asiti e matla ka ho fetisisa hobane e ionize ka ho felletseng, e hlahisa li-ion tse ngata tsa hydrogen. Li-ion tsa hydrogen ke mohloli oa asiti le ho lekanya matla a eona.
4. Tšebeliso e tloaelehileng ea HCl ke efe?
Lisebelisoa tse tala tsa lik'hemik'hale: tse sebelisetsoang ho kopanya li-chloride, hydrochlorides, metsoako ea organic, joalo-joalo.
Lisebelisoa tse tala tsa indasteri: tse sebelisoang ho metallurgy, electroplating, khatiso, ho etsa pampiri, joalo-joalo.
Litlhoko tsa letsatsi le letsatsi: tse sebelisetsoang ho hloekisa, ho thibela likokoana-hloko, ho hloekisa, joalo-joalo.
5. Likotsi tsa HCl ke life?
Corrosiveness: HCl ke asiti e matla e senyang letlalo, mahlo le tsela ea ho hema.
Ho teneha: HCl e na le phello e halefisang 'meleng oa motho' me e ka baka matšoao a kang ho khohlela, ho tiea sefuba le ho hema ka thata.
Carcinogenicity: HCl e nkoa e le kankere.
6. Ke hobane'ng ha HCl e sebelisoa meriana?
HCl e sebelisoa meriana, haholo-holo bakeng sa phekolo ea hyperacidity, esophageal reflux le mafu a mang.
7. Mokhoa oa ho lokisa HCl ho tsoa letsoai?
Qhala letsoai ka metsing, ebe o eketsa asiti e matla joalo ka sulfuric acid kapa hydrochloric acid ho hydrolyze ea hydrochloride.
NaCl + H2SO4 → HCl + NaHSO4
Letsoai le qhibiliha ka metsing, ebe khase ea chlorine e kenngoa ho chlorine letsoai.
NaCl + Cl2 → NaCl + HCl
A na u ka noa metsi a carbon dioxide?
