Chemistry. ib tug compound uas nws tus kheej uas twb muaj lawm molecules los yog ions ntawm ib tug nonmetal ( complexing agent ) tsim kev sib koom tes nrog cov hlau atom lossis ion. Ib qho chaw tsim los ntawm cov molecules uas cov neeg koom nrog tswj ntau yam ntawm lawv cov tshuaj lom neeg: receptor-hormone complex, enzyme-substrate complex.

Tsis tas li ntawd, dab tsi yog tus neeg sawv cev complexing siv rau?

Cov neeg ua haujlwm nyuaj tau siv dav hauv ntau qhov kev lag luam. Lawv yog siv los muab kev tswj xyuas cov kab hlau ions zoo hauv kev tu kev lag luam, textile, pulp thiab ntawv tsim, dej kho, kev ua liaj ua teb, zaub mov kev lag luam, thiab lwm yam.

Ib tug kuj yuav nug, vim li cas EDTA yog tus neeg sawv cev zoo? EDTA yog a zoo heev cheating tus neeg sawv cev , tso cai rau ntau yam kev sib khi hauv kev sib koom tes complex . Qhov no ua rau nws muaj peev xwm tshem tawm lwm cov ligands uas tsis xav tau vim yog entropy thiab thermodynamics, thiab yog li siv nyob rau hauv lub chaw soj nstuam, factories, thiab tshuaj. Qhov teeb meem nrog nws siv ntau dhau yog tias nws degrades rau hauv cov tshuaj lom.

Ntxiv mus, yog vim li cas ammonia yog ib tug zoo complexing neeg sawv cev?

Ammonia yog a zoo complexing agent vim nws yog a zoo luj base. Muaj ib khub ntawm electrons tam sim no ntawm nitrogen hauv ammonia , uas nws muaj peev xwm pub tau yooj yim rau lub hauv paus hlau atom thiab li no cov ntaub ntawv a complex nrog nws.

Dab tsi yog qhov nyuaj hauv chemistry?

A complex yog ib lub koom haum molecular tsim los ntawm cov koom haum xoob uas muaj ob lossis ntau lub koom haum molecular (ionic lossis uncharged), los yog cov khoom sib xws tshuaj hom. Kev sib txuas ntawm cov khoom feem ntau tsis muaj zog dua li covalent daim ntawv cog lus.
