Qhov sib txawv tseem ceeb ntawm cov ntsev ntsev thiab cov ntsev yooj yim yog cov kua qaub ntsev tsim cov tshuaj uas tsawg dua pH 7.0 thaum yaj hauv dej, qhov tseem ceeb ntsev tsim cov tshuaj uas siab dua pH 7.0 thaum yaj hauv dej.
Ib ntsev yog ib qho ionic compound uas muaj cation thiab anion. Nws yog ib qho khoom sib xyaw uas tsis muaj nuj nqis vim hais tias cov cations thiab anions ua ke nrog ib leeg nyob rau hauv txoj kev uas cov hluav taws xob nqi ntawm cations yog sib npaug nrog cov anions. Nyob ntawm cov ionic muaj pes tsawg leeg ntawm ntsev, cov khoom thiab reactivity tuaj yeem txiav txim siab. Yog li ntawd, peb muaj peev xwm categorize ib ntsev rau hauv peb pawg li acidic ntsev, yooj yim ntsev thiab nruab nrab ntsev.
Acidic S alt yog dab tsi?
Acidic ntsev yog cov ionic compounds uas tuaj yeem tsim cov kua qaub rau hauv dej. Qhov ntawd txhais tau tias; acidic ntsev tsim cov kua dej uas tsawg dua pH 7.0. Qhov no tshwm sim vim muaj cov hlau cation uas tuaj yeem hnov mob li Lewis acid lossis vim muaj hydrolysable protons. Feem ntau, acidic ntsev muaj hydrolysable protons. Cov hydrolysable protons no tuaj yeem muaj nyob hauv cation lossis anion.
Daim duab 01: Sodium Bisulfite yog ib qho Acid S alt
YHydrolysable Protons hauv Cation
Acidic ntsev uas muaj cations nrog hydrolysable protons feem ntau yog ammonium ions. Ammonium ions pib los ntawm ammonium ntsev. Tsis tas li ntawd, cov hydrolysable protons tuaj yeem tshwm sim hauv cov organic tebchaw uas muaj cov pab pawg protonated amine. E.g. ammonium ion, methyl ammonium ion, ethyl ammonium ion, anilinium ion, thiab lwm yam.
Hydrolysable Protons hauv Anion
Acidic ntsev yuav muaj cov hydrolysable protons hauv anion. Piv txwv xws li bisulfite ion, dihydrogen citrate, bioxalate ion, thiab lwm yam. Cov anions no muaj protons uas tsis muaj zog dissociated rau hauv dej.
Ntshav ntsev yog dab tsi?
Basic ntsev yog cov ionic compounds uas tuaj yeem tsim cov kev daws teeb meem yooj yim thaum so hauv dej. Qhov ntawd txhais tau tias; cov ntsev no tuaj yeem tsim cov tshuaj aqueous uas muaj pH siab dua 7.0. Feem ntau, cov ntsev yooj yim tuaj yeem deprotonate cov dej molecule thiab tsim hydroxide ions uas tuaj yeem ua rau cov hauv paus hauv cov kua dej.
Daim duab 02: Sodium Sulfide yog ib qho yooj yim ntsev
Qee yam piv txwv ntawm cov ntsev yooj yim suav nrog sodium bicarbonate, calcium carbonate, sodium acetate, potassium cyanide, thiab sodium sulfide. Cov ntsev no tuaj yeem cuam tshuam nrog dej, yuam cov dej molecules kom tshem tawm cov hydroxide ion.
Dab tsi yog qhov txawv ntawm Acidic S alt thiab Basic S alt?
Qhov sib txawv tseem ceeb ntawm cov ntsev ntsev thiab cov ntsev yooj yim yog cov kua qaub ntsev tsim cov tshuaj uas tsawg dua pH 7.0 thaum yaj hauv dej, thaum cov ntsev yooj yim tsim cov tshuaj uas siab dua pH 7.0 thaum yaj hauv dej. Ammonium ntsev, sodium bisulfite, thiab calcium oxalate yog qee cov piv txwv ntawm cov ntsev ntsev, thaum sodium bicarbonate, calcium carbonate, sodium acetate, potassium cyanide, thiab sodium sulfide yog qee cov piv txwv ntawm cov ntsev yooj yim.
Hauv qab infographic qhia txog qhov sib txawv ntawm acidic ntsev thiab ntsev yooj yim.
Summary – Acidic S alt vs Basic S alt
Nyob ntawm cov ionic muaj pes tsawg leeg ntawm ntsev, cov khoom thiab reactivity tuaj yeem txiav txim siab. Yog li ntawd, peb muaj peev xwm categorize ib ntsev rau hauv peb pawg li acidic ntsev, yooj yim ntsev thiab nruab nrab ntsev. Qhov sib txawv tseem ceeb ntawm cov ntsev ntsev thiab cov ntsev yooj yim yog cov kua qaub ntsev tsim cov tshuaj uas tsawg dua pH 7.0 thaum yaj hauv dej, qhov tseem ceeb ntsev tsim cov tshuaj uas siab dua pH 7.0 thaum yaj hauv dej.
