Qhov Tseem Ceeb Qhov Sib Txawv - Tus Neeg Ua Haujlwm Ua Haujlwm vs Chelating Agent

Chelation yog tsim los ntawm chelate. Ib qho chelate yog ib lub voj voog uas muaj lub hauv paus hlau atom txuas rau yam tsawg kawg yog ob lub atoms. Feem ntau, cov hlau ion nyob rau hauv ib qho kev daws tsis nyob ib leeg. Hlau ions tuaj yeem txuas nrog lwm cov hlau ions thiab tsim cov saw hlau. Yog hais tias tsis yog, hlau ions ua complexes nrog non-metal ions los yog molecules. Cov complexes no hu ua coordination compounds. Cov molecules lossis ions uas koom nrog hauv cov txheej txheem nyuaj no tuaj yeem muab faib ua ob hom ua cov neeg ua haujlwm complexing thiab chelate agents. Qhov sib txawv tseem ceeb ntawm tus neeg sawv cev complexing thiab chelating tus neeg sawv cev yog tus neeg sawv cev complexing yog ib qho ion, molecule lossis ib pab pawg ua haujlwm uas tuaj yeem khi nrog cov hlau ion los ntawm ib lossis ob peb lub atoms los tsim ib qho chaw loj thaum tus neeg sawv cev chelating yog ib qho khoom sib txuas uas tuaj yeem khi nrog ib qho. hlau ion los tsim ib tug chelate los ntawm ob peb atoms nyob rau hauv tib molecule.

Tus Neeg Ua Haujlwm Ua Haujlwm Dab Tsi yog Dab Tsi?

Ib tus neeg ua haujlwm nyuaj tseem hu ua ligand. Ib tug complexing neeg sawv cev yog ib hom tshuaj muaj peev xwm los khi nrog hlau ions los yog lwm yam tshuaj nyob rau hauv ib tug system los ntawm nws ib leeg los yog ntau qhov chaw. Cov chaw no muaj ib khub ntawm electrons uas tuaj yeem pub dawb rau d orbitals ntawm cov hlau ion, tsim kev sib koom ua ke. Qhov no ua rau muaj kev sib koom ua ke. Ligands tuaj yeem nyob ib puag ncig cov hlau ion lossis tuaj yeem ua tus choj ntawm ob lub hlau ions. Ib tug complexing neeg sawv cev yuav yog ib tug ion, molecule los yog ib tug functional pab pawg neeg ntawm ib tug molecule. Ib tus neeg sawv cev sib tw tuaj yeem muaj ib qho chaw sib khi lossis ntau qhov chaw sib khi.

Tus neeg saib xyuas Chelating yog dab tsi?

Tus neeg sawv cev chelating kuj yog hom ligand, tab sis tsis zoo li lwm cov ligands, cov neeg ua haujlwm chelating tuaj yeem khi rau cov hlau ion nrog ntau lub atoms hauv tib lub molecule. Tus neeg sawv cev chelating yog cov tshuaj sib xyaw uas tuaj yeem khi rau ib qho hlau ion los ntawm ntau lub atoms tam sim no hauv cov molecule. Cov atoms no muaj ib khub uas tuaj yeem pub dawb rau qhov khoob d orbitals ntawm cov hlau atom. Qhov no txhais tau hais tias, tsis zoo li lwm cov ligands, chelate agents yog multidentate ligands, thiab tsis muaj monodentate chelating agents. Piv txwv li, ib qho ethylenediamine molecule tuaj yeem tsim ob txoj kev sib koom tes nrog Nickel (II) atom. Txij li thaum Nickel (II) atom tuaj yeem tsim rau 6 daim ntawv cog lus, peb lub ethylenediamine molecules yuav khi nrog ib qho Nickel (II) atom.

Dab tsi yog qhov zoo sib xws ntawm Complexing Agent thiab Chelating Agent?

  • Ob tus neeg sawv cev thiab cov neeg ua haujlwm chelate yog ligands uas tuaj yeem khi nrog qee yam tshuaj hloov pauv.
  • Ob lub tebchaw no tsim kev sib koom tes nrog cov hlau ions los ntawm kev pub ib khub ntawm electrons rau d orbitals ntawm ib lub hlau.

Tus Neeg Ua Haujlwm Ua Haujlwm vs Chelating Agent

Tus neeg sawv cev ua haujlwm yog ib qho ion, molecule lossis ib pab pawg ua haujlwm uas tuaj yeem khi nrog hlau ion los ntawm ib lossis ntau qhov sib koom ua ke. Tus neeg sawv cev chelating yog cov tshuaj lom neeg uas tuaj yeem khi nrog cov hlau ions los ntawm ntau qhov kev sib koom tes ua ke los tsim kom ruaj khov, dej-soluble complexes.
Txawm qhov chaw sib khi
Ib tus neeg ua haujlwm nyuaj yuav muaj ib qho lossis ntau qhov chaw sib khi. Tus neeg sawv cev chelate muaj ntau qhov chaw sib khi tab sis tsis yog ib qho chaw khi ib qho molecule.
Number of Atoms koom
Ib tus neeg ua haujlwm nyuaj tuaj yeem khi nrog cov hlau ion los ntawm ib qho atom lossis ntau lub atoms. Tus neeg sawv cev chelating khi nrog cov hlau ion nrog tsawg kawg ob lub atom, tab sis tsis nrog ib lub atom.
Nature of Agent
Tus neeg sawv cev ua haujlwm tuaj yeem yog ion, molecule lossis pab pawg ua haujlwm. Tus neeg sawv cev chelate yog ib txwm muaj cov organic molecule.
Nature of Binding
Tus neeg sawv cev sib txuas tuaj yeem khi nrog cov hlau ion los ntawm ib puag ncig nws lossis ua tus choj uas txuas ob lub hlau ions. Tus neeg sawv cev chelate ib txwm khi nrog cov hlau ion los ntawm ib puag ncig nws, ua ib qho chelate.
Cov neeg ua haujlwm nyuaj tuaj yeem yog monodentate lossis multidentate. Chelating agents tsis tuaj yeem ua monodentate; lawv ib txwm multidentate.

Summary – Complexing Agent vs Chelating Agent

Ligands yog hom tshuaj lom neeg uas tuaj yeem khi nrog cov hlau ions los ntawm kev sib koom ua ke. Complexing agents thiab chelating agents yog cov ligands uas muaj txiaj ntsig zoo hauv kev lag luam. Lub ntsiab sib txawv ntawm complexing tus neeg saib xyuas thiab chelating tus neeg sawv cev yog complexing tus neeg sawv cev yog ib tug ion, molecule los yog ib tug ua hauj lwm pab pawg neeg uas yuav khi nrog ib tug hlau ion los ntawm ib tug los yog ob peb atoms los tsim ib tug loj complex whereas ib tug chelate agent yog ib tug compound uas yuav khi nrog. Ib qho hlau ion los tsim cov chelate los ntawm ntau lub atoms hauv tib lub molecule.
