Ntshiab cobalt tsis yaj hauv dej, tab sis yuav yaj (los yog react) nrog acids. Compounds uas tsis yog soluble hauv dej yog cobalt carbonate thiab cobalt oxide. Compounds uas yog soluble hauv dej yog cobalt nitrate thiab cobalt sulfate.
Yog li, yog cobalt sulfate soluble?
Cov khoom, kev npaj, thiab cov qauv Cobalt (II) sulfate heptahydrate zoo li liab monoclinic crystals uas liquify ib ncig ntawm 100 ° C thiab ua anhydrous ntawm 250 ° C. Nws yog soluble hauv dej, me ntsis soluble hauv ethanol, thiab tshwj xeeb tshaj yog soluble hauv methanol. Cov ntsev yog paramagnetic.
Puas yog cobalt sulfide soluble hauv dej? Txog Cobalt (II) Sulfide Feem ntau cov hlau sulfate tshuaj sib xyaw yog yooj yim soluble hauv dej rau kev siv xws li kev kho dej, tsis zoo li fluorides thiab oxides uas zoo li yuav insoluble.
Tsis tas li ntawd, qhov solubility ntawm cobalt yog dab tsi?
2.1 Solubility cov ntaub ntawv Rau pragmatic yog vim li cas, cobalt compounds muab faib ua ob pawg, cov soluble nyob rau hauv dej nyob rau theem siab dua 0.1 g / l, thiab cov tsis zoo soluble hauv dej nyob rau theem qis dua 0.1 g / l.
Yuav ua li cas ua cobalt sulfate?
Cobalt sulfate tuaj yeem npaj los ntawm kev ua pa cobalt hlau los yog cobalt oxide / hydroxide nrog aqueous sulfuric acid. Cua sov qhov kev daws teeb meem kom tshem tawm cov dej yuav muab cov ntaub ntawv hydrated cobalt sulfate . Yog tsis muaj dej cobalt (II) sulfate yog xav tau, cov hydrated crystals yuav tsum tau rhuab mus rau 250 ° C kom tshem tawm cov dej.

Puas yog amine soluble hauv NaOH?
Cov dej-insoluble compounds uas yog solublein 5% NaOH ces sim nrog 5% sodium hydrogen carbonate (NaHCO3). Yog tias cov khoom sib xyaw tau yaj hauv 5% HCl, nws yog anamine. Amines yog cov hauv paus organic uas hnov mob nrog HClto tsim cov dej-soluble amine ntsev, raws li qhia hauv Equation4
Puas yog pentyl acetate soluble hauv dej?
Cov no yog cov carboxylic acid derivatives uas cov pa roj carbon atom los ntawm pawg carbonyl txuas nrog alkyl los yog aryl moiety los ntawm cov pa atom (ua ib pawg ester). Pentyl acetate yog ib qho hydrophobic molecule heev, xyaum insoluble (hauv dej), thiab kuj nruab nrab
Puas yog eugenol soluble hauv dej?
Eugenol yog ib tug tswv cuab ntawm cov chav kawm allylbenzene ntawm cov tshuaj sib txuas. Nws yog ib qho tseeb rau daj ntseg oily kua muab rho tawm los ntawm tej yam tseem ceeb roj tshwj xeeb tshaj yog los ntawm clove roj, nutmeg, cinnamon, thiab nplooj nplooj. Nws yog me ntsis soluble hauv dej thiab soluble hauv cov kuab tshuaj organic
Puas yog Isopentyl cawv soluble hauv dej?
Isoamyl Cawv yog cov kua uas tsis muaj xim nrog pungent saj thiab tsis pom zoo aroma. Nws yog soluble hauv cawv thiab ether tab sis me ntsis soluble hauv dej
Puas yog langbeinite dej soluble?
Langbeinite yog dej soluble tag nrho, tab sis nws qeeb qeeb dua li lwm cov chiv K vim tias cov khoom muaj denser dua lwm qhov chaw K. Yog li ntawd, nws tsis haum rau dissolving thiab thov los ntawm irrigation systems tshwj tsis yog tias finely av
