A chemistry student wants to determine the concentration of copper(II) ions in a solution using electrochemical methods. The student prepares a copper electrode and a reference electrode, and sets up a cell with the copper electrode immersed in the solution and the reference electrode in the salt bridge. The standard cell potential is measured to be +0.34 V. If the student knows that the reduction of copper(II) to copper occurs at the copper electrode, what is the concentration of copper(II) ions in the solution?
