Kuenzanisa kweMasero eVoltaic neMasero eElectrolytic
Kwemazana emakore, electrochemistry yave iri bazi guru rekemistri, richidzidza hukama huripo pakati pemagetsi nemakemikari. Mukudzidza kwe electrochemistry, mhando mbiri dzinozivikanwa dzemasero e electrode masero e voltaic (anonziwo galvanic cells) nemasero e electrolytic. Kunyangwe ese ari maviri achishanda papfungwa imwe chete—kushandurwa kwesimba remakemikari kuita simba remagetsi kana zvinopesana—ane misiyano yakakosha. Chinyorwa chino chichakurukura zvakadzama kuenzanisa pakati pemasero e voltaic nemasero e electrolytic, ichifukidza tsananguro dzawo, misimboti yekushanda, maumbirwo, mashandisirwo, uye kukosha kwehupenyu hwezuva nezuva.
Tsanangudzo uye Nheyo Dzekutanga
Sero reVoltaic: Sero reVoltaic, kana kuti sero reGalvanic, chinhu chinoburitsa magetsi kuburikidza nekuita kwemakemikari kwe redox (kuderedza oxidation). Musero iri, kuita kwemasimba emagetsi kunogadzira simba remagetsi rinogona kushandiswa pazvinangwa zvakasiyana-siyana.
Masero eElectrolytic: Masero eElectrolytic anoshanda nenzira yakasiyana. Anoshandisa simba remagetsi rinobva kune imwe nzvimbo yekubuda kuti aite kuti redox reaction iitike. Izvi zvinogona kuitika chete kana paine magetsi anomanikidza maion kuti aite.
Maumbirwo eMasero eVoltaic neMasero eElectrolytic
Maumbirwo eSero reVoltaic:
1. Anode neCathode: Musero revoltaic, anode ndiyo electrode apo oxidation inoitika, uye cathode ndiyo electrode apo kudzikiswa kunoitika.
2. Munyu: Chikamu ichi chinoshanda kuchengetedza kuenzana kwemagetsi nekubvumira maion kufamba kubva kuhafu yesero kuenda kune imwe pasina kusanganisa zvakananga.
3. Maelectrolyte: Maelectrolyte zvinhu zvine maayoni akasununguka zvinofambisa magetsi pakati pemaelectrode.
Maumbirwo eSero reElectrolysis:
1. Maerekitirodhi: Musero remagetsi, maerekitirodhi anewo anode necathode, asi mabasa awo anochinja-chinja kana tichienzanisa nemasero evoltaic. Anode ndiyo electrode yakanaka, uye cathode ndiyo electrode isina kunaka.
2. Simba Rinobva: Simba rinoshandiswa kumanikidza redox reaction rinobva kune rimwe simba rekunze rakadai sebhatiri kana rimwe simba reDC.
3. Maelectrolyte: Maelectrolyte ari mumasero eelectrolytic akakoshawo kuti ape maion anodiwa pakuita kwekuita.
Prinsip Kerja
Nheyo yekushanda kweVoltaic Cell:
Sero revoltaic rine mahafu maviri emasero akabatana nemunyu bhiriji newaya inobatanidza. Kuita kwe redox kunoitika mukati mesero iri. Kana maerekitironi maviri akasiyana (kazhinji simbi) anyikwa mu electrolyte, maion esimbi anobva mu anode (electrode isina kunaka) anochinja okisijeni oburitsa maerekitironi. Maerekitironi aya anoyerera nepawaya inobatanidza kuenda ku cathode (electrode yakanaka), uko maion ari mu solution anowana maerekitironi obva adzikiswa.
Nheyo yekushanda kweElectrolytic Cell:
Musero remagetsi, sosi yemagetsi yekunze inoshandisa voltage kuti ifambise magetsi kuburikidza neelectrolyte. MaIon ari mu electrolyte solution anokwezvwa nema electrodes ane machaji akasiyana - ma cations ku cathode (uko kunoderedza kunoitika) uye ma anions ku anode (uko kunoitika oxidation). Maitiro anoitika pa electrode yega yega anokonzera maitiro e redox asingazoitiki pasina sosi yesimba rekunze.
Shandisa Muhupenyu Hwezuva Nezuva
Mashandisirwo eMasero eVoltaic:
1. Mabhatiri: Mabhatiri ndiwo anonyanya kushandiswa nemasero evoltaic, anosanganisira mabhatiri ealkaline nemabhatiri e lithium-ion, anoshandiswa mumidziyo yemagetsi inotakurika, mota dzemagetsi, nezvimwe zvakawanda.
2. Kugadzira simbi nesimbi: Maitiro ekuputira simbi nejira rekudzivirira kuburikidza nemaitiro e redox anongoerekana aitika anoshandisawo musimboti we voltaic cell kudzivirira ngura.
Mashandisirwo eMasero eElectrolysis:
1. Kugadzirwa kweGasi: Masero eElectrolytic anoshandiswa kugadzira hydrogen neokisijeni kubva mumvura kuburikidza nemaitiro anozivikanwa se water electrolysis.
2. Kuisa simbi mu electroplating: Sero iri rinoshandiswawo mukuita kwekuisa simbi mu simbi kuti rive nerukoko rwekudzivirira kana rwekushongedza pane zvimwe zvinhu kuburikidza nekuita kusingangoerekana kwaitika.
3. Kugadzirwa kweMakemikoro: Masero eElectrolytic anoshandiswa mumaindasitiri kugadzira makemikari akadai sechlorine, sodium hydroxide, nezvimwe zvinhu zvakasiyana-siyana zveelectrolytic.
Kuenzanisa Kunokosha
1. Simba: Masero evoltaic anogadzira simba remagetsi kubva mukuita kwemakemikari asingafungidzirwi, nepo masero eelectrolytic achida simba remagetsi rekunze kuti aite maitiro emakemikari asingafungidzirwi.
2. Kutungamira kweReaction: Reaction yeRedox mumasero evoltaic inoitika yoga, nepo mumasero eelectrolytic, magetsi anokonzera redox reactions.
3. Maerekitirodhi: Musero revoltaic, anode iri negative uye cathode iri positive. Musero reelectrolytic, anode iri positive uye cathode iri negative.
4. Mashandisirwo: Masero evoltaic anowanzo shandiswa kugadzira magetsi zvakasununguka, nepo masero eelectrolytic achi shandiswa kuita mamwe maitiro emakemikari asingazoitiki ega.
Mhedziso
Masero ese ari maviri evoltaic neelectrolytic inyaya dzakakosha dzakachinja zvakanyanya zvinhu zvakawanda zvehupenyu hwemazuva ano, kubva pahunyanzvi hwekuchengetedza simba kusvika pakugadzira maindasitiri uye machira. Kunyange hazvo rimwe nerimwe riine misimboti yekushanda nemashandisirwo akasiyana, ese ari maviri anoratidza hukama hunoshamisa pakati pekuita kwemakemikari nesimba remagetsi. Kunzwisisa kusiyana kwawo nekufanana kunogona kuwedzera kunzwisisa kwedu kwekushandiswa kunogona kuitwa ne electrochemistry mukugadzirisa matambudziko ezuva nezuva nekugadzira matekinoroji emangwana.
