Thaum Ca(NO3)2 yog yaj hauv H2O ( dej ) nws yuav tsis sib haum (solve) rau hauv NH4 + thiab 2NO3- ions. Los qhia tias lawv tau yaj hauv dej peb ua tau sau (aq) tom qab txhua. Cov (aq) qhia tau hais tias lawv yog aqueous – yaj hauv dej.
Ib yam li ntawd, yog calcium nitrate soluble lossis insoluble hauv dej?
Dej Acetone
Ib tug kuj nug, CA no3 2 puas tsim ions hauv dej? Piv txwv li, lub dej solubility ntawm calcium nitrate yog 121.2 g Ca ( NO 3 ) 2 rau 100 ml dej ntawm 25 ° C. Yog ntau Ca ( NO 3 ) 2 yog ntxiv rau cov tshuaj, nws yuav nyob twj ywm hauv cov khoom daim ntawv . Thaum peb hais ib ionic khoom yog insoluble nyob rau hauv dej , peb ua tsis txhais hais tias tsis muaj cov khoom dissolves.
Hauv qhov no, calcium nitrate puas yuav yaj hauv dej?
Calcium nitrate . Nws yog heev soluble thiab tsim cov tetrahydrate, Ca (NO3)2· 4 H2O yog kev daws yog evaporated rau dryness. Qhov no ntsev yog siab heev soluble nyob rau hauv dej thiab thiab yaj hauv cawv thiab acetone. Cov tetrahydrate melts nyob rau hauv nws tus kheej cov dej ntawm hydration ntawm 42.7 ° C thiab poob 4H2O molecules ntawm 132 ° C.
Yam khoom twg yuav sib cais thaum ntxiv rau dej?
NaOH yog Arrhenius puag vim nws dissociates hauv dej kom muab cov hydroxide (OH-thiab sodium (Na+) cov. Ib Arrhenius kua qaub yog li ntawd tej yam khoom uas ionizes thaum nws dissolves nyob rau hauv dej muab cov H+los yog hydrogen, ion.

Puas CuSO4 dissociate hauv dej?
Thaum CuSO4 los yog CuSO4. 5H2O yog yaj hauv H2O (dej) lawv yuav dissociate (solve) rau hauv Cu 2+ thiab SO4 2- ions. Cov (aq) qhia tau hais tias lawv yog aqueous – yaj nyob rau hauv dej
Puas yog ch3ch2oh dissociate hauv dej?
CH3CH2OH, lub npe hu ua ethanol, yog ib qho cawv uas muaj cov saw hlau luv luv thiab cov pab pawg hydrophilic. Cawv muaj peev xwm yaj hauv dej vim yog pawg cawv thaum kawg, tab sis raws li cov saw hlau carbon loj hlob ntev dua los yog loj dua (vim yog branching), solubility txo
Puas yog calcium hydroxide soluble hauv dej?
Dej Ib yam li ntawd, koj tuaj yeem nug, puas yog Ca Oh 2 soluble lossis insoluble hauv dej? Ca (OH ) 2 Nws tsuas yog me ntsis soluble hauv dej (0.16g Ca (OH ) 2 / 100g dej ntawm 20 ° C) tsim cov tshuaj hu ua txiv qaub dej. Lub solubility txo qis nrog nce kub.
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Puas yog HCl dissociate hauv dej?
Thaum HCl molecules yaj lawv dissociate rau H + ions thiab Cl- ions.HCl yog ib tug muaj zog acid vim nws dissociates yuav luag tag. Los ntawm qhov sib txawv, cov kua qaub tsis muaj zog xws li acetic acid (CH3COOH) tsis cuam tshuam zoo hauv dej - ntau H + ions tseem nyob hauv cov molecule
