Qhov sib txawv tseem ceeb ntawm anode thiab cathode yog qhov anode yog qhov zoo tshaj plaws thaum cathode yog qhov tsis zoo.

Anodes thiab cathodes yog electrodes nrog opposite polarity. Txhawm rau paub qhov txawv ntawm anode thiab cathode, peb yuav tsum xub nkag siab tias lawv yog dab tsi. Anodes thiab cathodes yog electrodes uas yog siv los ua hluav taws xob tam sim no rau hauv lossis tawm ntawm ib qho khoom siv uas siv hluav taws xob. Ib qho electrode yog cov khoom siv uas tso cai rau tam sim no hla nws. Cov electrodes feem ntau yog ua los ntawm cov hlau xws li tooj liab, npib tsib xee, zinc, thiab lwm yam, tab sis qee cov electrodes kuj ua los ntawm cov hlau tsis zoo li carbon. Tsis tas li ntawd, ib qho electrode ua tiav ib lub voj voog los ntawm kev hla tam sim no los ntawm nws.

Anode yog dab tsi?

Lub anode yog cov electrode uas tam sim no tawm ntawm lub xov tooj ntawm tes thiab qhov chaw oxidation tshwm sim. Peb kuj hu nws qhov zoo electrode. Lub roj teeb yooj yim muaj peb qhov loj: anode, cathode thiab electrolyte. Kev lig kev cai, cov electrodes yog nyob rau ntawm qhov kawg ntawm lub roj teeb. Thaum peb txuas cov xaus nrog hluav taws xob, tshuaj lom neeg cov tshuaj tiv thaiv pib hauv lub roj teeb. Ntawm no, electrons tau cuam tshuam thiab yuav tsum tau rov ua dua. Lawv sib ntaus sib tua thiab txav mus rau cathode, uas muaj tsawg dua electrons. Qhov no sib npaug electrons thoob plaws hauv cov tshuaj (electrolyte).

Daim duab 01: Zinc Anode

Feem ntau, tam sim no ntws tawm ntawm cathode thaum lub cuab yeej tawm. Txawm li cas los xij, cov kev taw qhia tam sim no thim rov qab thaum lub cuab yeej raug them thiab cathode pib ua haujlwm raws li anode thaum lub anode dhau los ua cathode.

Nyob rau hauv thawj lub xovtooj ntawm tes lossis lub roj teeb, cov terminals tsis rov qab, uas txhais tau hais tias anode yuav zoo ib yam. Qhov no yog vim peb ib txwm siv cov cuab yeej no los tso tawm hluav taws xob tam sim no. Tab sis nyob rau hauv cov ntaub ntawv ntawm ob lub hlwb los yog roj teeb, cov electrodes yog reversible raws li lub ntaus ntawv tso tawm, tab sis kuj tau txais tam sim no rau them.

Cathode yog dab tsi?

Cov cathode yog cov electrode uas tam sim no nkag mus rau ntawm tes thiab txo qis. Peb tuaj yeem hu nws tsis zoo electrode thiab. Txawm li cas los xij, cov cathode tuaj yeem ua rau tsis zoo hauv cov hlwb electrolytic thiab zoo hauv cov hlwb galvanic.

Lub cathode muab cov khoom siv hluav taws xob rau cations (cov nqi them zoo ions). Cov ions no ntws mus rau cathode los ntawm electrolyte. Tsis tas li ntawd, cov cathodic tam sim no yog qhov ntws ntawm electrons los ntawm cathode mus rau cations hauv kev daws. Txawm li cas los xij, cov ntsiab lus cathode thiab anode yuav xa mus rau cov ntsiab lus sib txawv hauv cov ntawv thov sib txawv.

Qhov txawv ntawm Anode thiab Cathode yog dab tsi?

Anode yog cov electrode uas tam sim no tawm ntawm lub xov tooj thiab qhov chaw oxidation tshwm sim thaum cathode yog cov electrode uas tam sim no nkag mus rau ntawm tes thiab txo qis. Qhov sib txawv tseem ceeb ntawm anode thiab cathode yog tias anode yog lub davhlau ya nyob twg zoo thaum cathode yog lub davhlau ya nyob twg tsis zoo. Txawm li cas los xij, tseem muaj cov electrodes bipolar uas tuaj yeem ua haujlwm raws li ob qho tib si anodes thiab cathodes. Feem ntau, anode nyiam cov anions thiab cathode nyiam cov cations, uas tau coj mus rau npe cov electrodes xws li.

Summary – Anode vs Cathode

Anode yog cov electrode uas tam sim no tawm ntawm lub xov tooj thiab qhov chaw oxidation tshwm sim thaum cathode yog cov electrode uas tam sim no nkag mus rau ntawm tes thiab txo qis. Qhov sib txawv tseem ceeb ntawm anode thiab cathode yog tias anode yog lub davhlau ya nyob twg zoo thaum cathode yog lub davhlau ya nyob twg tsis zoo.
