Qhov Tseem Ceeb - Cuprous vs Cupric
Cov cations ruaj khov tsim los ntawm tooj liab, uas yog ib qho d thaiv cov khoom, yog cuprous cation thiab cupric cation. Cov cuprous thiab cupric ions txawv ntawm ib leeg raws li lawv cov kev teeb tsa hluav taws xob. Qhov sib txawv tseem ceeb ntawm cuprous thiab cupric yog tias cuprous yog tooj liab 1 + cation whereas cupric yog tooj liab +2 cation.
Cuprous yog dab tsi?
Lub npe cuprous muab rau +1 cation tsim los ntawm tooj liab atom. Nws yog denoted los ntawm Cu+1 Electron configuration ntawm tooj liab atom yog [Ar] 3d10 4s1Thaum lub cuprous cation raug tsim, lub electron configuration yog [Ar] 3d10 4s0Yog li ntawd, lub cuprous cation yog tsim thaum ib tug electron raug tshem tawm ntawm lub tooj liab atom. Txij li thaum lub cuprous cation tuaj yeem khi nrog tsuas yog ib qho anion nrog -1 oxidation xeev, lub cuprous cation hu ua monovalent cation. Lub electron configuration ntawm cuprous cation yog ruaj khov heev. Yog li muaj, ntau lub tebchaw tsim los ntawm cov cation no. Qee qhov piv txwv tau qhia hauv qab no:
- Cuprous oxide (Cu2O)
- Cuprous iodide (CuI)
- Cuprous sulfide (Cu2S)
Lub zog hydration ntawm ib lub molecule lossis ion yog lub zog tso tawm thaum ib lub mole ntawm qhov sib xyaw u8ndergo hydration (solution hauv dej).
Daim duab 01: Lub Atomic Structure ntawm tooj liab
Lub khob ion muaj lub zog qis dua piv rau cupric ion vim tias d10 electron teeb tsa hauv lub khob ion ruaj khov dua li d 9electron configuration hauv cupric ion.
Cupric yog dab tsi?
Lub npe khob yog muab rau +2 cation tsim los ntawm tooj liab atom. Nws yog denoted los ntawm Cu2+ Electron configuration ntawm tooj liab atom yog [Ar] 3d10 4s1Thaum lub khob cation raug tsim, lub teeb tsa hluav taws xob yog [Ar] 3d9 4s0 Lub khob cation yog tsim thaum ob lub electrons raug tshem tawm ntawm tooj liab atom, muab lub atom rau 2+ hluav taws xob. Lub khob cation tuaj yeem khi nrog ob qho anions muaj -1 oxidation xeev lossis ib qho anion muaj -2 oxidation xeev. Yog li ntawd, lub cupric cation yog divalent cation. Cov tebchaw tsim nrog cov cation no suav nrog:
- Cupric oxide (CuO)
- Cupric iodide (CuI)
- Cupric sulfide (CuS)
Dab tsi yog qhov zoo sib xws ntawm Cuprous thiab Cupric?
- Ob lub Cuprous thiab Cupric yog cations tsim los ntawm kev poob ntawm electrons los ntawm ib tug tooj liab atom.
- Ob leeg yog cations ruaj khov.
- Ob leeg muaj qhov zoo hluav taws xob.
- Ob leeg muaj tib lub atomic mass (vim qhov loj ntawm ib qho hluav taws xob tsis zoo).
Qhov txawv ntawm Cuprous thiab Cupric yog dab tsi?
