Vanadium pentoxide zoo nkaus li daj mus rau liab crystalline hmoov. me ntsis soluble hauv dej thiab denser dua dej.
YPuas yog vanadium pentoxide soluble hauv dej?
Vanadium, vanadium (IV) oxide, thiab vanadium (III) oxide yog insoluble hauv dej Cov dej solubilities ntawm vanadium (V) pentoxide, ammonium metavanadate (V), thiab sodium metavanadate (V) yog 700 mg / 1, 000 g (25 ° C), 4.8 × 104 mg / 1, 000 g (20 ° C), thiab 2.1 × 105 mg / 1, 000 g (25 ° C), raws.
YPuas vanadium yaj hauv dej?
Acid-base reactions
V2O5 yog amphoteric oxide. Tsis zoo li feem ntau cov hlau oxides, nws dissols me ntsis hauv dej muab cov daj daj, kua qaub.
Yuav ua li cas koj yaj vanadium pentoxide?

Puas yog methacrylic acid yaj hauv dej?
Nws yog soluble hauv dej sov thiab miscible nrog feem ntau cov kuab tshuaj organic. Methacrylic acid yog tsim nyob rau hauv ib tug loj scale raws li ib tug precursor rau nws esters, tshwj xeeb tshaj yog methyl methacrylate (MMA) thiab poly (methyl methacrylate) (PMMA) .
Puas yog nucleic acid yaj hauv dej?
Cov lus teb yooj yim rau nws yog yog, nucleic acids yog dej-soluble Nucleic acids yog soluble tag nrho hauv dej muab qhov polar xwm. Lub tsev blocks ntawm cov tshuaj hereditary DNA thiab RNA yog nucleotides uas muaj pyrimidine los yog purine nplhaib, pentose qab zib thiab ib pawg phosphate .
Puas yog roj yaj hauv dej?
Cov roj thiab cov rog tsis muaj qhov polar thiab yog li kom lawv yaj hauv dej lawv yuav tsum tau tawg qee cov dej hydrogen bonds. Dej yuav tsis ua no yog li ntawd cov roj thiaj yuam kom nyob sib nrug ntawm dej . Puas yog roj soluble hauv dej Yog los tsis yog?
Puas yog ferric chloride yaj hauv dej?
Iron(III) chloride yog cov tshuaj inorganic nrog cov mis. Kuj hu ua ferric chloride, nws yog ib qho kev sib xyaw ntawm cov hlau hauv lub xeev +3 oxidation. Yuav ua li cas thaum ferric chloride ntxiv rau dej? Ferric Chloride lossis Hlau (III) Chloride (FeCl3) yog siv los ua flocculant hauv kev kho cov dej phwj tuaj thiab cov dej haus.
Puas yog ester yaj hauv dej?
Esters tuaj yeem tsim cov ntawv cog lus hydrogen los ntawm lawv cov pa atoms mus rau hydrogen atoms ntawm cov dej molecules. Raws li qhov tshwm sim, esters me ntsis soluble hauv dejTxawm li cas los xij, vim tias esters tsis muaj hydrogen atom los tsim cov hydrogen daim ntawv cog lus rau cov pa atom ntawm cov dej, lawv tsis soluble dua li carboxylic acids .
