In the second titration, the addition of. β2. sodium thiosulfate masks the copper cation. According to the complexation constants, β10 = 1010.3for copper and β20 = 102.3 for zinc (9), the complexation of Cu2 is selective and Cu2 is þ þ masked. Thus, titration of this solution by EDTA is restricted to Zn2 cations.Web
