A moos tshuaj tiv thaiv yog a tshuaj tiv thaiv uas ua rau nce mus rau lub sij hawm tseem ceeb induction thaum lub sij hawm uas ib tug ntawm cov tshuaj laj, moos tshuaj , muaj ib tug tsawg concentration. Hauv daim ntawv no peb xav txog kev sib xyaw ua ke ntawm ob txoj kev sib txawv uas ua rau muaj qhov tshwm sim moos tshuaj tiv thaiv tus cwj pwm.
Yog li ntawd, vim li cas nws thiaj li hu ua lub moos tshuaj tiv thaiv?
Cov iodine moos tshuaj tiv thaiv yog ib qho kev ua yeeb yam nyiam tshuaj tiv thaiv hauv chav kawm chemistry. Ob lub kua ntshiab yog tov, ua rau lwm cov kua ntshiab. Cov tshuaj tiv thaiv yog hu ua moos tshuaj tiv thaiv vim tias lub sijhawm dhau mus ua ntej cov tshuaj hloov xim xiav nyob ntawm qhov ntau ntawm cov tshuaj pib.
Ib tug kuj tseem nug, qhov kev txiav txim dab tsi yog lub moos tshuaj tiv thaiv iodine? Iodine moos tshuaj tiv thaiv Cov tshuaj tiv thaiv Peb tab tom saib yog oxidation ntawm iodide ions los ntawm hydrogen peroxide nyob rau hauv acidic tej yam kev mob. Cov iodine yog tsim ua ntej raws li ib tug daj daj tov darkening rau txiv kab ntxwv thiab ces tsaus liab, ua ntej tsaus grey khoom iodine yog nag lossis daus.
Yog li ntawd, lub moos tshuaj tiv thaiv ua haujlwm li cas?
Cov tshuaj tiv thaiv Hauv qhov kev sim no yog hu ua iodine moos tshuaj tiv thaiv , vim hais tias nws yog cov molecular iodine (I2) uas dhau qhov kev hloov pauv tam sim ntawd. Thaum cov iodine concentration nce, nws reacts nrog cov hmoov txhuv nplej siab nyob rau hauv cov tshuaj los ua ib tug complex, tig nws ib tug sib sib zog nqus xiav-dub xim.
Vim li cas cov hmoov txhuv nplej siab siv hauv iodine moos tshuaj tiv thaiv?
Iodine moos . Potassium persulphate yog siv ua oxidize iodide ions rau iodine , nyob rau hauv lub xub ntiag ntawm hmoov nplej thiab ib qho me me ntawm thiosulphate ions. Thaum cov thiosulphate tas lawm (los ntawm tshuaj tiv thaiv nrog rau iodine ua), lub ntuj xiav iodine - hmoov nplej complex yog tsim.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Dab tsi yog qhov sib txawv ntawm lub cev thiab tshuaj tiv thaiv hauv chemistry?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj qhov sib txawv ntawm qhov muaj pes tsawg leeg
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
