Thaum twg CuCl2 yog yaj nyob rau hauv H2O (dej) nws yuav dissociate (dissolve) rau hauv Cu2+ thiab Cl-ions. Tus (aq) qhia tias lawv yog dej - yaj hauv dej.

Tsuas yog li ntawd, yog tooj liab chloride aqueous?

Aqueous tshuaj npaj los ntawm tooj liab (II) tshuaj chloride muaj ntau yam ntawm tooj liab (II) complexes nyob ntawm qhov concentration, kub, thiab muaj qhov ntxiv tshuaj chloride ions. Cov tsiaj no suav nrog xiav xim ntawm [Cu(H₂O)₆]²⁺ thiab xim daj lossis xim liab ntawm halide complexes ntawm cov mis [CuCl₂₊_x]^x⁻.

CuCl2 dissociate hauv dej? Thaum xub thawj, lub CuCl2 dissolves, tsim ib tug aqua tov. Qhov no yog vim yog complex ions hu ua [Cu(H2O)6]2+ tsim uas tso saib aqua rau cov neeg soj ntsuam. Thaum kawg, qhov kev daws teeb meem yog saturated thiab crystals tshwm. Cov txheej txheem no yog inevitable muab cov kua xeev ntawm dej thiab continual mov ntawm CuCl2.

Tom qab ntawd, puas yog CuCl2 soluble?

Dej

Puas yog CuCl2 yog roj?

Cupric chloride. Nqe lus piav qhia: Copper chloride zoo nkaus li cov hmoov daj-xim av (daim ntawv anhydrous) lossis ntsuab crystalline khoom (dihydrate). Noncombustible tab sis hydrogen chloride gas tuaj yeem tsim thaum kub hauv hluav taws.

Puas yog ClO2 aqueous?

Chlorine Dioxide. Chlorine dioxide (ClO2) yog cov tshuaj sib xyaw ua ke ntawm ib qho chlorine atom thiab ob lub atoms oxygen. Nws yog xim liab mus rau daj-ntsuab roj ntawm chav tsev kub uas yaj hauv dej

Puas yog calcium cyanide aqueous?

Calcium cyanide kuj hu ua dub cyanide, yog ib qho inorganic compound nrog cov mis Ca (CN) 2. Nws yog cov khoom dawb, txawm tias nws tsis tshua pom nyob hauv daim ntawv ntshiab. Calcium cyanide. Lub npe tsw ntxhiab hydrogen cyanide Ceev 1.853 (20 ° C) Melting point 640 ° C (1,184 ° F; 913 K) (decomposes) Solubility hauv dej soluble

Dab tsi yog qhov sib npaug ionic rau cov tshuaj tiv thaiv ntawm aqueous lead II nitrate nrog aqueous sodium bromide?

Cov tshuaj tiv thaiv ntawm aqueous sodium bromide thiab aqueous lead (II) nitrate yog sawv cev los ntawm qhov sib npaug net ionic equation. 2Br−(aq)+Pb2+(aq) →PbBr2(s) 2 B r − (a q) + P b 2 + (a q) → P b B r 2 (s)

Puas yog tag nrho cov tshuaj aqueous soluble?

Yog hais tias cov khoom tsis muaj peev xwm yaj nyob rau hauv dej, cov molecules tsim precipitate. Cov tshuaj tiv thaiv hauv cov tshuaj aqueous feem ntau yog cov tshuaj tiv thaiv metathesis. Soluble compounds yog aqueous, hos insoluble compounds yog precipitate
