Part 1 - Making solutions The following solutions should be made, you will need a total of 8 vials to make the solutions: - Acetate buffer ( 0.2MpH4.65) : - 0.2M sodium acetate (NaCH3COO) in 100mL of DI water - 0.2M acetic acid (CH3COO) in 100mL of DI water - You would make a dilution from the concentrated acid (Concentration of Common Acids/Bases (Concentrated)) Determine the amount of each to mix to make pH4.6 in 100mL total - Use the Buffer Reference Center. - Pb2+ solutions: 0.1M nitric acid (HNO3) in 50mL DI water. Use the link above HNO3 in 10mL. Pb2+ in 12mL of the 0.2MpH4.6 acetate buffer.
