Tshuaj Magnesium Hydroxide (Mg(OH)₂) tsis yog ib qho muaj zog electrolyte; Nws yog ib qho tsis muaj zog electrolyte vim nws tsis tawm ions thaum nws yaj hauv dej. Muaj zog ions, zoo li sodium chloride, tsoo txhua yam sib nrug, tab sis magnesium hydroxide tsuas yog ua qee yam ntawm nws. Vim li no, nws tuaj yeem siv rau hauv kev lag luam rau kev tswj cov txheej txheem tshem tawm. Txawm li cas los xij, vim tias nws yog cov lus teb tsis muaj zog, nws ua haujlwm zoo los tua hluav taws thiab ntxuav qhov chaw ib puag ncig.
Nkag siab Magnesium Hydroxide thiab Electrolyte Strength
Kev faib tawm ntawm cov electrolytes nyob ntawm qhov tseem ceeb ntawm lawv lub peev xwm los ionize tag nrho hauv cov tshuaj aqueous. Cov electrolytes muaj zog ua tiav ze li ntawm 100% ionization, thaum cov electrolytes tsis muaj zog tau txais ib nrab dissociation. Magnesium hydroxide poob rau hauv pawg tsis muaj zog electrolyte vim nws qhov tsis tshua muaj solubility hauv dej, kwv yees li 0.0009 g ib 100 mL ntawm 25 degree.
Molecular Structure thiab Ion Dissociation
Mg(OH)₂ yog tsim los ntawm cov molecules uas yog tsim los ntawm magnesium ions txuas rau ob pawg hydroxide los ntawm ions. Thaum cov tshuaj tov nrog dej, nws mus rau hauv cov txheej txheem sib npaug hauv qab no:
Mg(OH)₂(s) + 2OH⁻(aq)=Mg²⁺(aq)
Kev txhawb zog rau lub xeev ruaj khov los ntawm qhov sib npaug no. Qhov no txhais tau hais tias tsis muaj ntau ions hauv kev daws. Nws hloov cov lej conductivity nyob rau hauv ib txoj kev sib txawv dua li cov hauv paus muaj zog xws li sodium hydroxide lossis potassium hydroxide vim nws tsis ionize ntau npaum li cas.
Kev sib piv nrog cov Electrolytes muaj zog
Cov neeg uas yuav khoom rau kev lag luam feem ntau piv magnesium hydroxide rau cov ntsev muaj zog kom pom seb nws puas yuav ua haujlwm hauv qee qhov xwm txheej. Sodium chloride los yog hydrochloric acid yog cov khoom muaj zog uas tuaj yeem tawg txhua yam sib nrug. Qhov no ua rau nws muaj peev xwm ions txav tau sai thiab nrog ntau qhov kev txav mus los. Txawm li cas los xij, magnesium hydroxide maj mam tso hydroxide ions. Qhov no txhais tau hais tias pH tuaj yeem hloov pauv raws sijhawm yam tsis muaj kev hloov pauv sai ntawm cov tshuaj nyob ib puag ncig nws.
Kev tswj tus cwj pwm no muaj txiaj ntsig zoo hauv cov txheej txheem kev lag luam uas ua kom cov pH yog txoj cai ua kom cov cuab yeej los ntawm xeb thiab cov khoom kawg qhov zoo tas li. Nws tsis dhau -neutralize zoo li muaj zog alkaline tshuaj vim nws yog ib qho tsis muaj zog electrolyte.
Chemical Properties thiab Neutralization Mechanism
