Cov sulphate uas tsim nyob rau hauv daim hlau ntawm ib tug lead acid roj teeb yog hu ua lead sulphate los yog PBSO4. Cov electrolyte yog sib xyaw dej (H2O) & hydrochloric acid (HCL).
Tsuas yog li ntawd, roj teeb acid yog dab tsi?
Kev them nyiaj yug thiab tso tawm thaum lub roj teeb yog tag nrho them, lub phaj tsis zoo yog txhuas, cov electrolyte yog concentrated sulfuric acid , thiab cov phaj zoo yog txhuas dioxide. Yog tias roj teeb yog overcharged, electrolysis ntawm dej ua hydrogen gas thiab oxygen gas, uas ploj lawm.
Cov roj teeb cuam tshuam li cas rau chemistry? Roj teeb . Roj teeb siv a tshuaj tshuaj tiv thaiv rau ua ua hauj lwm rau tus nqi thiab tsim ib tug voltage ntawm lawv cov zis terminals. Lub ntsiab tseem ceeb yog hu ua electrochemical cell thiab ua rau siv cov tshuaj tiv thaiv oxidation / txo. Ib qho hluav taws xob hluav taws xob uas tsim hluav taws xob sab nraud yog hu ua voltaic cell.
Tsis tas li ntawd, Epsom ntsev ua dab tsi rau lub roj teeb?
Cov no ntsev tuaj yeem txo qhov kev tiv thaiv sab hauv kom muab cov sulfated roj teeb ob peb lub hlis ntxiv ntawm lub neej. Tsim nyog additives yog magnesium sulfate ( Epsom ntsev ), caustic soda thiab EDTA (EDTA yog crystalline acid siv hauv kev lag luam). Thaum siv Epsom ntsev , ua raws li cov kauj ruam yooj yim no los kho feem ntau pib roj teeb.
Yuav ua li cas yog tias koj kov roj teeb acid?
Qhov roj teeb kua qaub ”hauv lead roj teeb kua qaub yog sulfuric kua qaub , thiab thaum nws ua tau yuav horribly puas, txheej txheej ntawm daim tawv nqaij ua tau tiv nws ib pliag. Muaj lwm yam kua qaub uas tawm tsam cov ntaub so ntswg sai dua, thiab yuav ua kev puas tsuaj ua ntej koj tuaj yeem yaug.

Lub teeb sib tham txog tej yam ntuj tso thiab manmade qhov chaw ntawm lub teeb yog dab tsi?
Tej qhov chaw ntawm lub teeb muaj xws li lub hnub, hnub qub, hluav taws, thiab hluav taws xob nyob rau hauv cua daj cua dub. Tseem muaj qee cov tsiaj thiab nroj tsuag uas tuaj yeem tsim lawv tus kheej lub teeb, xws li fireflies, jellyfish, thiab nceb. Qhov no hu ua bioluminescence. Artificial light yog tsim los ntawm tib neeg
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 qhov voltage ntawm lub roj teeb charger?
Constant Voltage Lub qhov hluav taws xob tsis tu ncua yog ib qho DC fais fab mov uas nyob rau hauv nws daim ntawv yooj yim tshaj plaws yuav muaj ib kauj ruam ntawm transformer los ntawm lub mains nrog ib tug rectifier los muab DC voltage los them lub roj teeb. Xws li cov qauv yooj yim feem ntau pom muaj nyob rau hauv pheej yig lub tsheb roj teeb chargers
Cov roj teeb nickel cadmium yog dab tsi?
1.2 Cell Chemistry. Lub roj teeb nickel-cadmium muaj cov nickel-positive electrode (cathode) thiab cadmium-tsis zoo electrode (anode) hauv cov tshuaj potassium hydroxide. Nrog them, thermodynamically instable npib tsib xee (III)-hydroxide thiab siab dua hydroxides yog tsim los ntawm protonation ntawm nickel (II)-hydroxide
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
