Acid ntsev Cov ntsev tseem muaj hydrogen atom (s) los ntawm ib kua qaub uas tuaj yeem hloov tau los ntawm cov hlau ions ntxiv. Piv txwv li: NaHSO4, NaHCO3 thiab NaHS 3. Basic ntsev Cov ntsev muaj hydroxides ua ke nrog hlau ions thiab tsis zoo ions los ntawm ib tug kua qaub.
Raws li txoj cai, NaHS yog cov kua qaub?
NaHS yog ib qho tseem ceeb reagent rau cov synthesis ntawm cov organic thiab inorganic sulfur tebchaw, qee zaum ua cov khoom reagent, feem ntau yog cov tshuaj aqueous.
Sodium hydrosulfide.

Dab tsi ntawm ntsev hu ua acidic ntsev? Ib acid ntsev yog a ntsev tsim los ntawm ib nrab los yog tsis tiav neutralization ntawm ib tug dibasic los yog tribasic kua qaub xws li H2CO3, H2SO4, H3PO3, H3PO4 thiab lwm yam (polybasic acids). Qee qhov piv txwv ntawm xws li ntsev yog sodium bicarbonate (NaHCO3), sodium bisulfate (NaHSO4) thiab sodium Dihydrogenphosphate (NaH2PO4).
Ib yam li ntawd, tib neeg nug, yog sodium hydrosulfide yog cov kua qaub lossis lub hauv paus?
Ib qho tshuaj puag . Reacts nrog kua qaub kom tso tawm cov nplaim hluav taws kub thiab tshuaj lom gaseous hydrogen sulfide. Tsuav yog cov tshuaj khaws cia muaj zog alkaline, pH> 10, muaj tsawg heev tso H2S. Ntawm pH = 7, qhov feem pua ntawm H2S tso tawm yog ze rau 80%.
Dab tsi yog sodium hydrosulfide siv rau?
Sodium hydrosulfide , paub los ntawm nws cov cim tshuaj NaHS (feem ntau hais tias "nash") yog siv hauv tawv tanning, pulp thiab ntawv, tshuaj, dyeing, thiab ntxhia extraction industries. NaHS yog siv li cov khoom ntshiab (flake) los yog ntau dua li cov tshuaj hauv dej.
Pom zoo:
Puas yog ntsev daws acidic lossis yooj yim?
PH ntawm ntsev tov. Lub pH ntawm cov tshuaj ntsev yog txiav txim siab los ntawm tus txheeb ze lub zog ntawm nws ?conjugated acid-base khub. Cov ntsev tuaj yeem yog acidic, nruab nrab, lossis yooj yim. Cov ntsev uas tsim los ntawm cov kua qaub uas muaj zog thiab lub hauv paus tsis muaj zog yog cov ntsev ntsev, xws li ammonium chloride (NH4Cl)
Puas yog kev sib xyaw ntsev thiab kua txob yog lub cev lossis tshuaj lom neeg?
Piv txwv li, sib tov ntsev thiab kua txob tsim ib yam khoom tshiab yam tsis tau hloov cov tshuaj pleev ib ce ntawm ob qho tib si. Lawv kuj yog lub cev hloov pauv vim lawv tsis hloov qhov xwm txheej ntawm cov khoom
Puas yog NaHS yog electrolyte?
Sodium hydrosulfide yog cov tshuaj sib xyaw nrog cov mis NaHS. Nyob rau hauv sib piv nrog sodium sulfide (Na2S), uas yog insoluble nyob rau hauv cov organic solvents, NaHS, yog ib tug 1: 1 electrolyte, yog ntau soluble. Xwb, nyob rau hauv qhov chaw ntawm NaHS, H2S tuaj yeem kho nrog cov organic amine los tsim cov ntsev ammonium
Puas yog dej ntsev npau npau hloov lub cev?
Nws yog kev hloov ntawm lub cev. Hauv kev daws cov sodium thiab chlorine muaj nyob hauv lawv cov ntawv ion, tab sis yog tias koj rhaub dej ntsev yog dab tsi tseem tshuav. Nws tseem yog ntsev thiab tsis tau hloov pauv los ntawm cov txheej txheem hydration thiab lub cev qhuav dej
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
