Isiliva Sulfate, ifomula yamakhemikhaliAG2SO4, iyinhlanganisela enezicelo eziningi ezibalulekile. Kuyinto eqinile emhlophe, engenamphundla ekhubazekile emanzini. Noma kunjalo, niniIsiliva SulfateIhlangana nokuxhumana namanzi, kwenzeka okuthile okuthokozisayo. Kulesi sihloko, sizobheka ukuthi kwenzekaniIsiliva Sulfateemanzini.
NiniIsiliva Sulfateingeziwe emanzini, ayincibiliki kalula. Ngenxa ye-solubility yayo ephansi, ingxenye encane kuphela yabahlanganisi abayingcolisa ama-ion aso - Isiliva (AG +) ne-Sulfate (So4 ^ 2- 2- 2- 2- 2-). Ukuchithwa okulinganiselwe kweIsiliva Sulfatekuholela kusisombululo esicacile nesingenamibala njengoba izinhlayiya ezingezinhle zixazululwa ezansi kwesitsha.
Kodwa-ke, ukufakwa kweIsiliva Sulfateinganqotshwa ngokusebenzisa amandla okwengeziwe angaphandle. Ngokwesibonelo, ukusonta kweIsiliva SulfateIngathuthukiswa uma izinga lokushisa lamanzi likhuphuka noma i-acid eqinile (njenge-sulfuric acid) yengezwa ohlelweni. Kulokhu, kwakhiwa ama-ions amaningi esiliva nama-sulfate kanye nekhambi ligcwele ngokwengeziwe. Lokhu kukhuphuka kwe-solubal kuvumela ukuxhumana okungcono phakathiIsiliva Sulfatenamanzi.
Isici esijabulisayo sokuxhumana phakathiIsiliva Sulfatenamanzi ukwakheka kwama-ion abukenyana. I-ion eyinkimbinkimbi iqukethe i-ion ephakathi yensimbi ezungezwe ama-ligands (ama-athomu, ama-ion noma ama-molecule aboshwe ngensimbi). Endabeni yesiliva Sulfate, kwakhiwa ama-ions abukeziwe lapho ama-molecule wamanzi afaka ama-sulfate ion eboshelwe esiliva, akha inkimbinkimbi yamanzi efana ne-AG (H2O) N +. Lezi zinhlobo zine-soubity elilinganiselwe emanzini, ngaleyo ndlela zanda ukuzibandakanya okuphelele kweIsiliva Sulfate.
Ukuvuselelwa kwemvumeIsiliva SulfateEmanzini akugcini ekuziphatheni kwayo kokuchithwa. Iphinde ibe nokuphendula okujabulisayo kwe-redox. Isibonelo, uma i-zinc yensimbi ingezwa kwisixazululo esiquketheIsiliva Sulfate, ukusabela okuhlanganyelwe kwenzeka. Ama-athomu ama-zinc asabela nge-sulfate ion, esusa ama-ion wesiliva engxenyeni futhi akha i-zinc sulfate. Lokhu kusabela kudala ukuthi insimbi yensimbi ifakwe endaweni ye-zinc, ikhiqiza ushintsho lombala obonakalayo.
Ekuphetheni, yizeIsiliva SulfateNgokuvamile kubhekwa njengokungabonakali emanzini, ukuziphatha kwayo ezixazululweni zamanzi anolwazi kuyinkimbinkimbi ngokwedlula umcabango. Ukungeza izinto zangaphandle, njengokushisa okwandayo noma ukuba khona kwamakhemikhali athile, kungakhulisa insomity yayo futhi kuholele ekwakhekeni kwama-ions abucayi. Ngaphezu kwalokho,Isiliva SulfateKukhombisa ukusatshalaliswa kabusha ngendlela yokuphendula kabusha kwe-redox nezinye izinto, njengoba kufakazelwa ukusabela okubangela nge-zinc yensimbi. Sekukonke, ukuqonda ukuziphatha kwesulfate sesiliva in Amanzi abucayi ukuthola izinhlelo ezahlukahlukene ezinkambu ezinjenge-chemistry, imboni, nesayensi yezemvelo.
