kua qaub. compound uas tsim hydrogen ions hauv kev daws . puag. compound uas ua hydroxide ions hauv kev daws . tsis pub.
Hais txog qhov no, dab tsi yog qhov sib xyaw uas tsim cov hydrogen ions hauv kev daws teeb meem?
kua qaub. a compound uas tsim hydrogen ions hauv cov kua , yog a hydrogen - ion pub, los yog ib qho electron-pair acceptor. acidic daws . ib yam daws hauv qhov twg hydrogen - ion concentration yog ntau dua li hydroxide- ion concentration.
Ib sab saum toj no, puas yog qhov sib xyaw ua ke uas tsim cov hydroxide ions thaum yaj hauv dej? Lub hauv paus Arrhenius yog ib yam khoom uas muab OH-, los yog hydroxide, ion thaum nws yaj hauv dej. Arrhenius kua qaub suav nrog cov tebchaw xws li HCl, HCN, thiab H2YOG4 uas ionize hauv dej muab H+ ion. Arrhenius bases suav nrog ionic compounds uas muaj OH- ion, xws li NaOH, KOH, thiab Ca(OH)2.
Yog li ntawd, dab tsi yog qhov sib xyaw uas ua rau ntau tshaj ntawm hydrogen ions hauv dej?
Acid. A compound uas ua rau ntau tshaj ntawm hydrogen ions hauv dej.
Dab tsi yog hydronium ion H + muaj nyob hauv kev daws ntawm nws tus kheej?
Raws li H+ ions yog tsim, lawv khi nrog H2O molecules nyob rau hauv lub daws los ua H3O+ (the hydronium ion ). Qhov no yog vim hydrogen ions ua tsis yog muaj nyob rau hauv aqueous daws, tab sis coj daim ntawv ntawm cov hydronium ion , H3O+.

Cov txheej txheem ntawm kev tsim cov kev daws teeb meem yog dab tsi?
Kev daws yog tsim thaum ib yam khoom hu ua thesolute 'dissolves' rau hauv lwm yam khoom hu ua hnyav.Dissolving yog thaum lub solute tawg los ntawm ib tug loj siv lead ua ntawm molecules mus rau ntau me me los yog ib tug molecules. Lawv ua qhov no los ntawm rub tawm cov ions thiab tom qab ntawd ncig cov ntsev molecules
Dab tsi yog qhov sib xyaw ua ke uas ua rau ntau tshaj ntawm hydrogen ions hauv dej?
Acid. Ib qho kev sib xyaw ua ke uas ua rau ntau tshaj ntawm hydrogen ions hauv dej
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem. Total Number of Points Number of 2-Point Baskets Number of 3-Point Baskets 17 4 (8 ntsiab lus) 3 (9 points) 17 1 (2 points) 5 (15 points)
Dab tsi yog qhov concentration ntawm hydronium ions nyob rau hauv ib qho kev daws teeb meem?
Cov dej ntshiab yog suav tias yog nruab nrab thiab qhov concentration ntawm hydronium ion yog 1.0 x 10-7 mol / L uas yog sib npaug rau hydroxide ion concentration
