Na2HPO 3 yog tsim thaum ob acidic hydrogen yog hloov los ntawm sodium. Nws tsis muaj acidic hydrogen. Yog li, nws yog ib txwm sodium ntsev ntawm phosphorus kua qaub . Tab sis NaH2PO 3 yog ib acid ntsev raws li nws tseem muaj ib acidic los yog hloov tau hydrogen nyob rau hauv nws muaj pes tsawg leeg.
Hauv qhov no, nah2po2 puas yog ntsev ntsev?
NPO 2 tsis yog ib acidic ntsev.
Tom qab, lo lus nug yog, vim li cas Na2HPO4 yog cov ntsev ntsev? Na2HPO 4 yog amphoteric: sau ob qhov kev tshwm sim. N a X 2 H P O X 4 yog amphoteric, uas txhais tau hais tias nws tuaj yeem ua lub hauv paus lossis ua ib qho kua qaub nyob ntawm seb cov tshuaj twg lawv teb nrog. ✨ Ib ntsev tsim ntawm ib qho tsis muaj zog acid thiab lub hauv paus tsis muaj zog tuaj yeem ua rau nruab nrab, acidic , los yog yooj yim nyob ntawm seb tus txheeb ze zog ntawm lub kua qaub thiab base.
Kuj Paub, yog ib qho kua qaub ntsev?
Acid ntsev yog ib chav kawm ntsev uas tsim ib acidic tshuaj tom qab yaj nyob rau hauv ib qho hnyav. Nws tsim ua ib yam khoom muaj hluav taws xob ntau dua li cov kuab tshuaj ntshiab.
Vim li cas Na2HPO3 yog ntsev ib txwm?
Na2HPO 3 yog tsim thaum ob acidic hydrogens hloov los ntawm sodium. Hauv lwm lo lus, qhov no ntsev yog cov khoom ntawm kev ua tiav neutralization ntawm phosphoric acid los ntawm sodium hydroxide. Nws tsis muaj acidic hydrogen. Yog li, nws yog a ib txwm sodium ntsev ntawm phosphorus acid.

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 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 ntsev yaj hauv dej spontaneous?
Kev daws ntawm NaCl hauv dej muaj ntau qhov kev txiav txim tsawg dua li cov dej ntshiab thiab cov ntsev crystalline. Entropy nce txhua lub sij hawm ib tug solute dissolves nyob rau hauv ib tug hnyav. Txawm hais tias qhov hloov pauv enthalpy yog tus lej zoo, qhov kev sib cais yog tshwm sim vim hais tias Gibbs tsis muaj zog hloov pauv, G, yog qhov tsis zoo vim lub sij hawm entropy
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
