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?

A chemistry student needs to quantify the amount of iron (II) ions in a sample using colorimetry. The sample was prepared by dissolving a known mass of iron (II) sulfate in water, and the solution was diluted to a known volume. The student needs to determine the concentration of iron (II) ions in the original solution by measuring the absorbance of the sample using a colorimeter, and then using calibration curves to convert the absorbance to concentration. The student also needs to calculate the percentage error of the experiment and suggest ways to improve the accuracy of the results.
