The titration of Zn+2 and EDTA is carried out in the same manner as Mg2+ - EDTA titration (in fact, Zn metal may be used to standardize your EDTA solution). In this case, the ammonia from the pH 10 buffer serves and additional purpose. What is it? pH 10 buffer is made with 57 mL of concetrated NH3 (or NH4OH) and 7 g of NH4Cl and diluted to 100 mL with DI water
