Ions fe3+
WebNa metodologia, íons Fe 3+ são reduzidos a íons Fe 2+, em meio ácido ácido a quente, pela adição de solução de SnCl 2 gota-a-gota até desaparecimento da coloração amarela da solução; em seguida, solução de HgCl 2 em excesso é adicionada com a finalidade de oxidar Sn 2+ a Sn 4+ e um volume de solução contendo mistura de MnSO 4 e H 3 PO 4 … WebInterprétation : Les ions Fe3+ sont orange en solution aqueuse. L'ion permanganate est violet en solution aqueuse. L'apparition de la coloration orange de la solution est donc due à l'apparition des ions Fe 3+ (aq) dans la solution.
