Pelarutan serbuk perak dilakukan dengan pengadukan pada kecepatan 400 rpm selama 1,5 jam dan banyaknya Ag yang larut dianalisis dengan SSA. Dari penelitian yang telah dilakukan diperoleh konsentrasi ion Ag + maksimum yang larut dalam media air sebesar 1,49 x 10 -2 M dan dalam media campuran 60%(v/v) asetonitril-air sebesar 2,20 x 10 -2 M. Dengan perhitungan pelarutan perak, didapatkan energi bebas transfer standar (DG t 0 ) ion Ag + dari media air ke media campuran 60% (v/v) asetonitril-air ialah-971,94 joule mol -1 . Hasil penelitian menunjukkan bahwa dengan meningkatnya persentase asetonitril dalam media campuran asetonitril-air, maka besarnya DG t 0 cenderung makin negatif atau kelarutan ionAg + makin besar.}, issn = {2597-9914}, pages = {203--207} doi = {10.14710/jksa.3.3.203-207}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/18888} }
