Ans: Lub Cathode yog ib qho tsis zoo electrode, whereas lub anode yog ib tug zoo electrode Lawv yog li-hu vim hais tias cov cations, uas yog zoo them, tsiv mus rau qhov tsis zoo cathode.. Li no, lub npe hu ua cathode thaum cov anions migrate mus rau qhov zoo them anode, thiab thiaj li hu ua anode.

Puas yog anodes thiab cathodes tib yam?

Lub Anode yog qhov tsis zoo lossis txo cov electrodeuas tso tawm cov hluav taws xob rau sab nraud thiab oxidizes thaum lub sij hawm thiab cov tshuaj tiv thaiv electrochemical. Lub Cathode yog qhov zoo lossis oxidizing electrode uas tau txais cov hluav taws xob los ntawm cov hluav taws xob sab nraud thiab raug txo thaum lub sij hawm cov tshuaj tiv thaiv electrochemical.

Anode thiab cathodes yog dab tsi?

Ib anode yog ib qho hluav taws xob los ntawm cov khoom siv tam sim no(tus nqi zoo) ntws mus rau hauv lub cuab yeej los ntawm ib qho hluav taws xob sab nraud, thaum lub cathode yog electrode los ntawm cov pa tam sim no ntws tawm ntawm tus ntaus ntawv.

Qhov txawv ntawm cov hlau hauv anodes thiab cathodes yog dab tsi?

Anode - Cov electrode qhov twg cov tshuaj tiv thaiv galvanic tsim cov hluav taws xob - cov ions tsis zoo raug tso tawm thiab tsim cov ions zoo. Corrosion tshwm sim ntawm lub anode. Cathode - Cov electrode uas tau txais electrons - zoo ions raug tso tawm, tsis zoo ions raug tsim. Lub cathode tiv thaiv corrosion.

Puas cathodes lossis anodes nquag nquag?

2.4.

Piv txwv li, hlau thiab tooj liab electrodes raus rau hauv ib qho electrolyte (Fig. 2.5), sawv cev rau ib tug galvanic cell. Cov hlau zoo tshaj plaws tooj liab ua raws li cathode thiab ntau cov hlau ua haujlwm ua anode.
