Sodium selenate muaj cov qauv qhia pom Na2O4Se. Cov ntsev anhydrous thiab cov hydrate muaj qhov hnyav molecular ntawm 188.94 thiab 369.11, feem. Cov ntaub ntawv sib xyaw ua kom dawb, tsis muaj hluav taws xob muaju uas muaj qhov ntom ntom ntawm 3.098 thiab yog dej-soluble.
YPuas yog sodium selenite soluble hauv dej?
Sodium selenite zoo nkaus li cov xim dawb crystalline khoom. Soluble hauv dej thiab ntom dua dej. Kev sib cuag tuaj yeem ua rau tawv nqaij, qhov muag thiab cov mucous.
Cov mis rau sodium selenate yog dab tsi?
Ib qho tsis muaj ntsev sodium ntsev uas muaj selenate raws li kev tawm tsam. Sodium selenate yog cov tshuaj inorganic nrog cov qauv Na2SeO4, tsis txhob totaub nrog sodium selenite.
Ntau npaum li cas selenium hauv sodium selenite?
Raws li sodium selenite, cov tshuaj lom neeg mob ntev tau piav qhia txog 2.4 txog 3 milligrams ntawm selenium ib hnub.
Dab tsi yog cov txiaj ntsig ntawm sodium selenite?
Selenium activates anticancer agents, tiv thaiv kab mob plawv thiab vascular, nthuav tawm cov tshuaj tiv thaiv kab mob thiab tiv thaiv kab mob, thiab txhawb kev tiv thaiv kab mob [2]. Lub luag haujlwm lom neeg ntawm selenium yog raws li kev tiv thaiv kev xeeb tub thiab mob qog noj ntshav thiab kab mob plawv [41].

Puas yog cov txheej txheem soluble endothermic lossis exothermic?
Tus txheej txheem ntawm kev sib cais yog exothermic thaum ntau lub zog tawm thaum cov dej molecules "daim ntawv cog lus" rau cov kuab tshuaj dua yog siv los rub cov kua dej sib nrug. Vim tias muaj zog ntau dua li siv, cov molecules ntawm cov tshuaj txav nrawm dua, ua rau qhov kub thiab txias.
Puas yog tetraazole soluble hauv dej?
qis tetraazoles, RCN 4 H, zoo li qis carboxylic acids, RCO 2 H, yog s soluble hauv dej thiab tsis tuaj yeem yooj yim crystalized los ntawm nws. tetrazoles qis dua yog crystallized zoo tshaj plaws los ntawm cov kuab tshuaj xws li ethyl acetate los yog toluene-pentane sib tov.
Puas yog dej hydrophobic soluble?
Cov pab pawg ua haujlwm yog pawg ntawm cov atoms nrog cov qauv thiab cov haujlwm. Polar molecules Polar molecules Nyob rau hauv chemistry, polarity yog kev sib cais ntawm cov nqi hluav taws xob ua rau cov molecule lossis nws cov chemical pawgmuaj lub sijhawm hluav taws xob dipole, nrog qhov tsis zoo them kawg thiab qhov zoo kawg nkaus.
Puas yog epoxides dej soluble?
Nplhaib qhib ntawm arene oxide los ntawm dej muab trans 1, 2-diol los ntawm S N 2 mechanism. Cov diols no zoo li yog dej-solublethiab yooj yim tshem tawm ntawm lub cev. Hauv cov ntaub ntawv ntawm naphthalene, epoxide tsim ntawm C-1 rau C-2 daim ntawv cog lus es tsis yog C-2 rau C-3 daim ntawv cog lus.
Puas yog sodium acetate soluble hauv dej?
Sodium acetate, NaCH₃COO, kuj hu ua NaOAc, yog sodium ntsev ntawm acetic acid. Cov ntsev tsis muaj xim tsis muaj xim no muaj ntau yam kev siv. YPuas yog sodium acetate soluble lossis insoluble? Comment on solubility: Soluble in water thiab ethanol.
