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.
