- Deliquescent ntsev los yog cov khoom yog cov uas nqus dej noo los ntawm lawv qhov chaw nyob ib puag ncig. Nws muaj lub siab nyiam yaj hauv cov dej noo absorbed thiab tsim nws tus kheej tov. Qee qhov piv txwv yog: - Sodium Nitrate, Calcium Chloride thiab Potassium Oxide.
Ib yam li ntawd, tib neeg nug, Efflorescent ntsev yog dab tsi?
Eflorescence yog crystalline deposit ntawm ntsev uas tuaj yeem tsim thaum dej nyob hauv lossis ntawm cib, pob zeb, pob zeb, stucco lossis lwm qhov chaw hauv tsev. Nws muaj ib tug dawb los yog greyish tint thiab muaj ntsev deposits tshuav tom qab thaum dej evaporates.
Kuj Paub, yog sodium chloride yog Deliquescent? Feem ntau noj tsis zoo tshuaj yog ntsev. Thaum lub rooj ntsev los yog sodium chloride ( NaCl ) tej zaum noj tsis zoo Yog hais tias cov khoom me me thiab cov av noo siab heev, ntsev feem ntau suav hais tias yog hygroscopic. Vim lawv txoj kev sib raug zoo rau dej, noj tsis zoo Cov tshuaj pom siv raws li desiccants.
Ib yam li ntawd, tib neeg nug, dab tsi yog ib qho khoom tsis zoo?
A khoom deliquescent yog ib yam khoom uas yooj yim nqus dej tawm ntawm huab cua. Soluble ntsev yog cov piv txwv ntawm cov khoom tsis zoo . Cov no suav nrog aluminium chloride, sodium nitrate, calcium chloride thiab potassium oxide.
Puas yog qab zib yog Deliquescent?
Saum toj ib tus txheeb ze av ntawm kwv yees li 75 feem pua ntsev yuav txawm dhau los noj tsis zoo , txhais tau hais tias nws siv dej ntau heev kom nws dhau los ua kev daws teeb meem. Qab Zib kuj yog hygroscopic; nws tsim kev sib txuas tsis muaj zog nrog cov dej molecules hauv nws ib puag ncig. Qhov no yog vim qab zib absorbs dej los ntawm huab cua, uas ua rau lub ncuav qab zib moist.

Dab tsi yog lub npe ntsev tsim los ntawm neutralization ntawm hydrochloric acid thiab sodium hydroxide?
Kev piav qhia: Cov tshuaj tiv thaiv ntawm sodium hydroxide (NaOH) thiab hydrochloric acid (HCl) yog cov tshuaj tiv thaiv nruab nrab uas ua rau muaj ntsev, sodium chloride (NaCl), thiab dej (H2O). Nws yog ib qho tshuaj tiv thaiv exothermic
Dab tsi yog qhov tseem ceeb ntawm cov ntsev yaj hauv dej hiav txwv?
Ntsev nyob rau hauv dej hiav txwv los ntawm pob zeb nyob rau hauv av. Cov nag uas ntog rau hauv av muaj qee cov pa roj carbon dioxide yaj los ntawm cov huab cua ib puag ncig. Qhov no ua rau cov dej nag ua rau acidic me ntsis vim yog carbonic acid (uas tsim los ntawm carbondioxide thiab dej)
Dab tsi yog ntsev ntawm daim duab hauv daim iav dav hlau?
S.A.L.T. Yog daim duab pem hauv ntej, lossis qab daim iav. Puas yog daim duab ze dua lossis deb dua ntawm daim iav dua li qhov khoom
Puas yog NaHS yog ntsev ntsev?
Acid ntsev Cov ntsev tseem muaj hydrogen atom los ntawm cov kua qaub uas tuaj yeem hloov tau los ntawm cov hlau ions ntxiv. Piv txwv xws li: NaHSO4, NaHCO3 thiab NaHS 3. Basic ntsev Cov ntsev muaj cov hydroxides ua ke nrog cov hlau ions thiab cov ions tsis zoo los ntawm cov kua qaub
Puas yog NaH2PO3 yog ntsev ntsev?
Na2HPO3 yog tsim thaum ob lub acidic hydrogens hloov los ntawm sodium. Nws tsis muaj acidic hydrogen. Yog li, nws yog ib txwm sodium ntsev ntawm phosphorus acid. Tab sis NaH2PO3 yog cov ntsev ntsev vim nws tseem muaj ib qho acidic lossis hloov tau hydrogen hauv nws cov muaj pes tsawg leeg
