oxidation-reduction reactions. The first part of the experiment measures the standard electrode potentials of five various half cells against the Cu2+(1M)|Cu half cell. The last three half cells are prepared through electrolysis. The electrode potentials of all reactions are positive which means that they are spontaneous. There is a significant percent difference from the theoretical and the experimental standard electrode potentials. The sources of error are incorrect solution preparation and contaminated materials

Resting potential is created by a transport protein called the sodium-potassium pump. Resting potential occurs when ions are distributed unequally on the inside and outside of cells‚ and when cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition‚ the inside of the cell has a high concentration of K+ and the outside of the cell has a low concentration of K+. K+ will naturally diffuse
