Sirivha sulfate, makemikari formulaAg2SO4, musanganiswa une zvakawanda zvakakosha zvinoshandiswa.Iro jena, risinganhuhwi risinganyunguriki mumvura.Zvisinei, rinhisirivha sulfateinosangana nemvura, mamwe maitiro anofadza anoitika.Munyaya ino, tichaona zvinoitikasirivha sulfatemumvura.
Rinisirivha sulfateinowedzerwa kumvura, haina kunyungudika nyore.Nekuda kwekudzika kwayo kunyungudika, chikamu chidiki chete chemukomboni chinopatsanura muchikamu chayo ions - sirivheri (Ag +) uye sulfate (SO4 ^ 2-).Yakaganhurirwa kupera kwesirivha sulfateinoguma nemhinduro yakajeka, isina ruvara sezvo zvimedu zvisina kunyunguduka zvinogara pasi pegaba.
Nekudaro, iyo insolubility yesirivha sulfateinogona kukurirwa nokushandisa simba rokuwedzera rokunze.Somuenzaniso, solubility yesirivha sulfateinogona kuvandudzwa kana tembiricha yemvura yakawedzera kana asidi yakasimba (senge sulfuric acid) inowedzerwa kuhurongwa.Muchiitiko ichi, mamwe sirivha uye sulfate ions anoumbwa uye mhinduro inowedzera kuzara.Izvi zvinowedzera solubility zvinobvumira kudyidzana kuri nani pakatisirivha sulfateuye nemvura.
Chinhu chinonakidza chekudyidzana pakatisirivha sulfateuye mvura ndiko kuumbwa kwemaion yakaoma.Ioni yakaoma ine ioni yesimbi yepakati yakakomberedzwa nemaatomu, ayoni kana mamorekuru akasungirirwa kusimbi.Kana iri sirivheri sulfate, maion akaoma anoumbwa apo mamorekuru emvura anotsiva maion e sulfate anosungwa nesirivheri, achigadzira mvura yakaoma seAg(H2O)n+.Aya macomplexes ane mashoma solubility mumvura, nekudaro achiwedzera kunyungudika kwese kwesirivha sulfate.
The reactivity ofsirivha sulfatemumvura haina kuganhurirwa pakuita kwayo kunyungudika.Iyo zvakare inosangana inonakidza redox reactions.Semuenzaniso, kana metallic zinc yakawedzerwa kune mhinduro inesirivha sulfate, kushanduka kwemaitiro kunoitika.Maatomu ezingi anopindirana neayoni esulfate, achibvisa maion esirivha mukomboni uye kugadzira zinc sulfate.Kuita uku kunoita kuti simbi yesimbi iiswe pane zinc pamusoro, ichigadzira shanduko yeruvara inooneka.
Mukupedzisa, kunyange zvakadarosirivha sulfateinowanzoonekwa seisinganyunguriki mumvura, hunhu hwayo mumigero ine aqueous yakaoma kupfuura yaimbofungwa.Kuwedzera zvinhu zvekunze, sekuwedzera tembiricha kana kuvepo kwemamwe makemikari, zvinogona kuwedzera kunyungudika kwayo uye kutungamirira mukuumbwa kwemaion akaoma.Uyezve,sirivha sulfateinoratidza reactivity muchimiro redox reactions nezvimwe zvinhu, sezvinoratidzwa ne displacement reactions with metallic zinc.Pakazara, kunzwisisa maitiro esirivha sulfate in mvura yakakosha kune dzakasiyana siyana dzekushandisa muminda senge chemistry, indasitiri, uye sainzi yezvakatipoteredza.
