What is the concentration of copper ions (Cu2+) in a sample of industrial wastewater? Use voltammetry to determine the amount of copper ions present in the sample and calculate the concentration in parts per million (ppm).Note: The student should be familiar with the principles of voltammetry and know how to prepare and analyze samples for this technique.

What is the concentration of copper ions (Cu2+) in a 100 mL sample of wastewater if 4652 coulombs of electricity are needed to completely oxidize all the copper ions present? The electrolysis is carried out using a current of 0.25 amperes for a period of 6 minutes. Assume that the only copper present is in the form of Cu2+.
