Redox

iman kara redox waa iman kara koronto in ururayaa on koronto la dhigayaa in xal ay ku jiraan xaddi gaar ah oo nidaamyada redox. Nidaamka noocan oo kale ah waxaa, marka la soo gaabiyo, maqaalka loo gudbin doonaa sida OBC. Xaalad lagama maarmaan u ah dhismaha iyo qamaar dhismaha noocan oo kale ah waa in koronto ah taas oo ay dhacdo, waxa uu ahaa bir inert.

Karo SMF, ama nidaamka redox, - waa xal, kaas oo ah walaxda waa la joogo in qaabkeeda oxidized iyo hoos isku mar. Mid kasta oo ka mid ah noocyadan waa in la sameeyay kale oo ka soo koorsada of falcelinta ee nooca redox ah. Mid ka mid ah erayga, foomka walxaha la joogo in xal sida, wuxuu noqon doonaa kara karo. Tusaale ahaan ugu fudud ee nidaamka redox waa xal, taas oo ay jiraan anions ama siifilisku ka mid ah biraha, laakiin ay valency waa ka duwan yahay.

In nidaamka sida, guurka ka mid foomka inay maal kale waxaa la sameeyaa iyadoo adeegsanayo kala iibsiga electron jihada ka foomka hoos. Nidaamka noocan oo kale ah waxaa ka mid ah ensaymes-mareenka, taas oo ay ka kooban waxaa ku jira hemin. Kartidooda redox waxaa lagu go'aamiyaa iyadoo la raacayo sharciyo u furan Claus Peters. In dunida noolaha, waxaa jira xaddi ku filan hababka redox, taas oo guurka waxaa lagu fuliyaa ma by kala iibsiga ee electrons, laakiin tiro la mid ah protons.

Under xaaladaha shaybaarka awood redox waxaa lagu go'aamiyaa iyadoo la isticmaalayo habka potentiometric. Its technology waa sida soo socota: Labada koronto ku inert waxaa marka hore lagu meeleeyay xal isku mid ah, ka dibna xal kala duwan, laakiin kuwaas oo bond electrolytic xiran jidaynayey xal ah in ay isku daraan. Laga soo bilaabo qadarka farqiga waxaa lagu go'aamiyaa xubno kala iibsiga iyo qiimaha iman kara.

Si loo qiyaaso habka Colorimetric sidoo kale loo isticmaalaa meesha cabbirka waxaa lagu fuliyaa by tilmaamayaasha gaarka ah.

Marka laga nooca cabbirka in la fahamsan yahay in qiimaha falimihiisii kale ka iman kara redox sida regenerative tilmaame universal a nidaamka guryaha redox, iyo awooda lagu qayilo ay. Hannaanka geedi socodka redox marayo waa mid fudud oo ku filan si ay u fahmaan. In qaabka guud ee SMF la a iman kara sare, waxaa oxidizes ku SMF, taas oo ay leedahay awood ah redox of magnitude yar. Cabbiraad ee iman kara ayaa go'aaminaya cadadka tamarta kaas oo ku jira in geedi socodka redox ka dhacda dabiiciga ah.

Nidaamkan waa mid ku siin, waayo, jiritaanka shaqeeyo kasta sababtoo ah dhaqdhaqaaqa electron xidhxidhan, oo sidaas daraaddeed, la sii daayo of xaddi gaar ah oo tamar si ay u ilaaliyaan homeostasis iyo cusboonaysiinta gacanta.

Tusaale ahaan, sida caadiga ah, ama laga yaabo in redox caadiga ah ee jidhka bini'aadamka waa in kala duwan ee - 200 MV - + 100 MV, oo tilmaamaysa in nooca hoos deegaanka gudaha. Marka lagu qiyaaso iman kara, waa in ka dhergin xaaladda, si ay u helaan xogta lagu kalsoonaan karo barbardhig, cabbiraadda waa in loo sameeyey sida waafaqsan shuruudaha physico-kiimikada isku. Haddii la mid ah sida oo u shaqeeyo aadanaha, shuruudaha si loo cabbiro iman kara redox oo biyo ah, waxaa suurtagal ah in la ogaado in ay qiimaha had iyo jeer waa ay wanaagsan tahay, waana qiimo ka 200 300 MV. Meelaan ah ee qiimaha awooda biyaha iyo jidhka bini'aadamka noocan oo kale ah, waxay sheegeen in electrons ah ee jirka ku dhaqmaan in a sii badan firfircoon ka badan in xal aqueous. Xaqiiqo ahaan, taas macnaheedu waa biyo in la tilmaamayaasha sida, galaya jidhka bini'aadamka galo si toos ah in geeddi-socodka lagu qayilo ka.

hantida waxaa loo isticmaalaa hagaajinta ee tilmaamayaasha sida OBC, taas oo ah jirkeena. Biyaha, isagoo ka iman kara a index xun, waxaa loo isticmaalaa sida qayb weyn (oo madax banaan) diyaarinta daroogada in xasilinta dheelitirka redox ah.
