Iseli Yomthofu-Asidi kaPlanté

Wonke amaseli ngaphambi kuka-1859 ayehamba ngendlela eyodwa kuphela. Uyawakhipha amandla bese uzinki isiphelile; ukulungisa okukodwa kwakuyinsimbi entsha. Ngo-1859 uGaston Planté wasonga amaqoqo amabili omthofu ahlukaniswe yizingcezu zenjoloba abe uhlaka olusontekile, wawafaka ku-asidi ye-sulfuric ehlanjululiwe, wathola ukuthi angakwazi ukuphusha ukusabela kubuyele emuva ngogesi bese ekhipha amandla futhi. Wakubika e-Academy of Sciences yaseFrance ngo-1860. Ikhemistri icacile ngendlela engavamile ngalokhu. Uma igcwele, iseli yi-lead dioxide ibhekene nomthofu onjengesipontshi ku-asidi; uma iphelile, womabili amapuleti ayinto efanayo, i-lead sulfate, futhi ingxenye enkulu ye-asidi isiphenduke amanzi. Leyo ngxenye yokugcina yingozi ewusizo: i-electrolyte ISABELA, ayibuki nje, ngakho ubukhulu bokuminyana kukaketshezi butshela isimo sokushajwa. Isindanti nethumbu lengilazi kuyisikali sikaphethiloli, futhi ayikho enye iseli ejwayelekile enikeza lokho. Okwabiza uPlanté kwakuyisikhathi. Wayengenzi amapuleti — wayenza iqoqo lomthofu bese ENZA amapuleti ngalo, ngokushaja nokukhipha amandla kaninginingi kuze kube ubuso buphenduke bujule ngokwanele ukuze bubambe umthwalo osebenzayo. Ukwakhiwa kwakuthatha amasonto kuya ezinyangeni, futhi yingakho umthofu-asidi wawukhona iminyaka engamashumi amabili nambili ngaphambi kokuba noma ubani akwazi ukuwuthengisa. Leyo nkinga eyodwa yiyona yonke indaba yepulani elilandelayo kulolu chungechunge. Akazange ayifake ilungelo lobunikazi. Iseli elidubula cishe zonke izimoto emhlabeni langena emhlabeni njengephepha elifundwe phambi kwe-academy.
