1.2 Cell Chemistry. Cov npib tsib xee – cadmium roj teeb muaj ib npib tsib xee - zoo electrode (cathode) thiab a cadmium -tsis zoo electrode (anode) nyob rau hauv poov tshuaj hydroxide tov. Nrog them, thermodynamically instable npib tsib xee (III)-hydroxide thiab ntau dua hydroxides yog tsim los ntawm protonation ntawm npib tsib xee (II) - hydroxide.
Tsis tas li ntawd, cov roj teeb nickel cadmium siv rau dab tsi?
A npib tsib xee - cadmium roj teeb ( NiCd los yog NiCad ) yog rechargeable roj teeb siv rau portable computers, xyaum, camcorders thiab lwm yam me me roj teeb -cov khoom siv ua haujlwm uas yuav tsum tau muaj hluav taws xob tawm. NiCds siv electrodes ua los ntawm npib tsib xee oxide hydroxide, hlau cadmium thiab alkaline electrolyte ntawm potassium hydroxide.
Dab tsi electrolyte siv hauv nickel cadmium roj teeb? poov tshuaj hydroxide
Tsuas yog li ntawd, cov roj teeb nickel cadmium puas muaj kev phom sij?
“Dry cell” roj teeb , xws li alkaline, npib tsib xee cadmium , thiab carbon zinc tsis tau teev tseg raws li phom sij cov ntaub ntawv lossis cov khoom txaus ntshai hauv Teb Chaws Asmeskas thiab cov kev cai thoob ntiaj teb. Thaum xa khoom los ntawm lub nkoj hauv qhov ntau tshaj 100 kg lawv yuav tsum raug xa mus raws li kev tswj hwm tag nrho hauv Chav Kawm 9 phom sij cov khoom siv / cov khoom txaus ntshai.
Leej twg invented nickel cadmium roj teeb?

Lub kinetic txoj kev xav ntawm cov teeb meem cuam tshuam li cas rau cov kua dej thiab cov pa roj?
Lub kinetic molecular txoj kev xav ntawm cov teeb meem hais tias: Cov teeb meem yog tsim los ntawm cov khoom uas hloov mus tas li. Tag nrho cov khoom muaj lub zog, tab sis lub zog sib txawv nyob ntawm qhov ntsuas kub ntawm cov qauv ntawm cov teeb meem nyob hauv
Dab tsi yog qhov txawv ntawm nickel plating thiab electroless nickel plating?
A. Electrolytic npib tsib xee yog tso siv DC tam sim no, thaum Electroless Ni yog autocatalytic deposition. Electroless Ni ua rau plating ntawm cov tuab tuab thoob plaws hauv ib feem, thaum electrolytic Ni daim hlau ua kom tuab dua nyob rau hauv qhov chaw siab tam sim no
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Cov roj teeb puas muaj teeb meem?
Cov roj teeb hlawv tawm cov pa phem, uas ua rau lub ntsws ua pa. Cov roj teeb tawm: Tsis txhob cuam tshuam cov hluav taws xob xau, nws tuaj yeem ua rau mob hnyav thiab / lossis puas tsuaj rau daim tawv nqaij, mucous membrane lossis ob lub qhov muag
Dab tsi yog cov tshuaj electrolyte rau cov roj teeb?
Nyob rau hauv lub roj teeb lead acid, sulfuric acid thiab dej yog cov electrolyte. Nws kuj muab cov sulfate ions xav tau rau kev tso tawm ntawm oxygen molecules rau hauv kev daws. Rau cov tshuaj electrolyte, dej distilled yog qhov kev xaiv zoo tshaj plaws
