Sodium Carbonate
Inorganic compound soda tshauv, tab sis cais raws li ntsev, tsis alkali.Sodium carbonate yog hmoov dawb, tasteless thiab tsw, yooj yim soluble nyob rau hauv dej, aqueous tov yog alkaline, nyob rau hauv cov huab cua ntub yuav nqus noo noo clumps, ib feem ntawm sodium bicarbonate.Kev npaj ntawm sodium carbonate suav nrog cov txheej txheem alkali sib koom ua ke, txheej txheem ammonia alkali, txheej txheem Lubran, thiab lwm yam, thiab nws tuaj yeem ua tiav thiab ua kom zoo los ntawm trona.

Selenium
Selenium ua hluav taws xob thiab cua sov.Cov hluav taws xob conductivity hloov pauv nrog kev siv ntawm lub teeb thiab yog cov khoom siv photoconductive.Nws tuaj yeem cuam tshuam ncaj qha nrog hydrogen thiab halogen, thiab hnov mob nrog hlau los tsim selenide.
-
Potassium Carbonate
Cov tshuaj inorganic, yaj raws li cov hmoov dawb crystalline, soluble hauv dej, alkaline hauv cov tshuaj aqueous, insoluble hauv ethanol, acetone, thiab ether.Muaj zog hygroscopic, raug huab cua tuaj yeem nqus cov pa roj carbon dioxide thiab dej, mus rau hauv potassium bicarbonate.

Sodium sulfate
Sodium sulfate yog sulfate thiab sodium ion synthesis ntawm ntsev, sodium sulfate soluble hauv dej, nws cov tshuaj feem ntau yog nruab nrab, soluble hauv glycerol tab sis tsis soluble hauv ethanol.Inorganic tebchaw, siab purity, zoo hais ntawm anhydrous teeb meem hu ua sodium hmoov.Dawb, tsw, iab, hygroscopic.Cov duab yog xim tsis muaj xim, pob tshab, cov muaju loj lossis cov pob zeb me me.Sodium sulfate yooj yim nqus dej thaum raug huab cua, ua rau sodium sulfate decahydrate, tseem hu ua glauborite, uas yog alkaline.

Sodium Silicate
Sodium silicate yog ib hom inorganic silicate, feem ntau hu ua pyrophorine.Na2O·nSiO2 tsim los ntawm qhuav casting yog loj thiab pob tshab, thaum Na2O·nSiO2 tsim los ntawm ntub dej quenching yog granular, uas yuav siv tau tsuas yog thaum hloov mus rau hauv kua Na2O·nSiO2.Cov khoom uas muaj Na2O·nSiO2 cov khoom yog: ① bulk solid, ② hmoov khoom, ③ instant sodium silicate, ④ xoom dej sodium metasilicate, ⑤ sodium pentahydrate metasilicate, ⑥ sodium orthosilicate.

Calcium Chloride
Nws yog ib qho tshuaj ua los ntawm chlorine thiab calcium, iab me ntsis.Nws yog ib tug raug ionic halide, dawb, tawg tawg los yog hais nyob rau hauv chav tsev kub.Cov ntawv thov feem ntau suav nrog brine rau cov khoom siv tub yees, cov neeg ua haujlwm deicing thiab desiccant.

Sodium Chloride
Nws qhov chaw yog dej hiav txwv, uas yog lub ntsiab ntawm ntsev.Soluble hauv dej, glycerin, me ntsis soluble hauv ethanol (cawv), kua ammonia;Insoluble nyob rau hauv concentrated hydrochloric acid.Impure sodium chloride yog deliquescent hauv huab cua.Qhov kev ruaj ntseg yog qhov zoo, nws cov tshuaj aqueous yog nruab nrab, thiab kev lag luam feem ntau siv cov txheej txheem ntawm electrolytic saturated sodium chloride tov los tsim hydrogen, chlorine thiab caustic soda (sodium hydroxide) thiab lwm yam khoom siv tshuaj (feem ntau hu ua chlor-alkali kev lag luam) kuj tseem siv tau rau ore smelting (electrolytic molten sodium chloride crystals los tsim active sodium hlau).

Boric acid
Nws yog cov hmoov dawb crystalline hmoov, nrog rau kev xav zoo thiab tsis muaj ntxhiab tsw.Nws acidic qhov chaw tsis yog muab protons los ntawm nws tus kheej.Vim tias boron yog ib qho hluav taws xob tsis muaj hluav taws xob, nws tuaj yeem ntxiv hydroxide ions ntawm dej molecules thiab tso tawm protons.Ua kom zoo dua ntawm cov cuab yeej tsis muaj hluav taws xob no, cov khoom sib txuas polyhydroxyl (xws li glycerol thiab glycerol, thiab lwm yam) tau ntxiv rau cov khoom ruaj khov kom ntxiv dag zog rau lawv cov acidity.
