Yog, xws li cov tshuaj tiv thaiv muaj ntau heev nyob rau hauv yooj yim inorganic chemistry. (1) Muaj zog puag tau yooj yim teb nrog rau ntsev ntawm qaug zog puag thiab tshem nws. Lwm yam alkalis (muaj zog hauv paus ) zoo li NaOH thiab KOH kuj tau yooj yim tso ammonia ntawm kev ua kom sov nrog ammonium ntsev.

Ua raws li qhov no hauv kev xav, yuav ua li cas tshwm sim thaum lub ntsev cuam tshuam nrog lub hauv paus?

Thaum muaj acid thiab a puag muab tso ua ke, lawv teb neutralize cov acid thiab puag khoom, tsim ib ntsev . H(+) cation ntawm cov kua qaub ua ke nrog OH (-) anion ntawm lub puag tsim dej. Lub compound tsim los ntawm cation ntawm lub puag thiab anion ntawm cov kua qaub hu ua a ntsev.

Kuj Paub, ntsev ua rau pH li cas? Sodium Chloride Ob leeg ntawm lawv tsis hnov tsw nrog dej, yog li ntawd ntsev yuav tsuas yog hloov qhov ntim ntawm cov dej, tsis yog nws pH . Nyob rau hauv kev txiav txim rau txhua yam ntawm ntsev rau cuam tshuam tus pH (muaj peev xwm ntawm hydrogen), nws yuav tsum hnov mob nrog dej kom tso lossis khi cov hydrogen atoms los ntawm dej.

Hais txog qhov no, cov ntsev puas cuam tshuam nrog acids?

Hauv qhov no, lub zog kua qaub thiab ntsev react tsim kom muaj zog kua qaub thiab a ntsev . Yog li kuv twv, piv txwv li tag nrho cov no cov tshuaj tiv thaiv tshwm sim, thaum ib acid reacts nrog a ntsev , ib new kua qaub yog tsim thiab yog li yog ib tug tshiab ntsev.

Puas yog NaCl yog qhov nruab nrab?

Sodium chloride yog ntsev ntawm muaj zog acid HCl thiab muaj zog hauv paus NaOH. Raws li ntsev tov muaj cov sib npaug ntawm H + thiab OH- ions, aqueous tov ntawm NaCl yog nruab nrab nyob rau hauv qhov.

Lub kaum sab xis ntawm qhov cuam tshuam cuam tshuam li cas rau cov tsos ntawm cov ntshav?

Thaum cov ntshav raug cuam tshuam, cov tee dej tau tawg los ntawm huab cua. Thaum cov tee dej no tawm tsam ib qho chaw, cov duab ntawm cov stain hloov nyob ntawm lub kaum sab xis ntawm qhov cuam tshuam, kev tshaj tawm, kev ncua deb thiab hom ntog cuam tshuam. Raws li lub kaum sab xis ntawm qhov cuam tshuam hloov, yog li qhov tshwm sim ntawm qhov tshwm sim stain

Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?

Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai

Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?

Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus

Puas yog cov kev cuam tshuam cuam tshuam ib txwm endothermic?

Cov txheej txheem ntawm dissolving yog endothermic thaum tsawg zog tawm thaum dej molecules "daim ntawv cog lus" rau cov kuab tshuaj dua yog siv los rub cov kua sib nrug. Vim tias lub zog tsawg dua yog tso tawm ntau dua li siv, cov molecules ntawm cov tshuaj txav qeeb dua, ua rau qhov kub thiab txias
