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.
