Yuav ua li cas paub qhov txawv ntawm 5th roj teeb los ntawm 7th roj teeb?
1. Roj teeb:
Lub roj teeb hais txog ib feem ntawm qhov chaw ntawm lub khob, lub tank lossis lwm lub thawv lossis cov thawv sib xyaw uas muaj cov tshuaj electrolyte thiab cov hlau electrodes los tsim cov khoom siv hluav taws xob tam sim no, thiab tuaj yeem hloov hluav taws xob hluav taws xob rau hauv hluav taws xob. Nws muaj qhov zoo electrode thiab tsis zoo electrode.
Thib ob, lub hauv paus ntsiab lus roj teeb:
1: Hauv cov roj teeb tshuaj, qhov ncaj qha hloov pauv ntawm cov tshuaj siv hluav taws xob rau hauv hluav taws xob hluav taws xob yog qhov tshwm sim ntawm oxidation spontaneous oxidation, txo qis thiab lwm yam tshuaj lom neeg hauv lub roj teeb, uas yog nqa tawm ntawm ob lub electrodes feem.
2: Cov khoom siv hluav taws xob tsis zoo yog tsim los ntawm tus neeg sawv cev uas muaj qhov tsis zoo thiab ruaj khov hauv cov electrolyte, xws li cov hlau nquag xws li zinc, cadmium, thiab lead, thiab hydrogen lossis hydrocarbons.
3: Cov khoom siv zoo yog tsim los ntawm oxidants nrog lub peev xwm zoo thiab ruaj khov hauv cov electrolyte, xws li hlau oxides xws li manganese dioxide, lead dioxide, npib tsib xee oxide, oxygen lossis cua, halogens thiab lawv cov ntsev, oxoacids thiab lawv cov ntsev hauv chav kawm thiab lwm yam.
4: Electrolytes yog cov khoom uas muaj ionic conductivity zoo, xws li aqueous daws ntawm acids, bases, thiab ntsev, organic los yog inorganic non-aqueous daws, molten ntsev, los yog cov khoom electrolytes.
