Electrodeposition is the process by which metal ions are deposited by reduction onto a cathode surface. Different instability phenomena affect how these patterns form and which morphologies are observed. Surface tension plays an important role in the formation of patterns. As such, this paper seeks to understand the changes in pattern morphology that should be observed in an electrochemical cell when changing the surface tension of the electrolyte solution by changing its viscosity. Surface tension and viscosity are known to be related, and as one changes the other should change as well. Ethylene glycol has been chosen for the purposes of this experiment. When added in a weight percent basis to the electrolyte solution, changes in morphology were indeed observed. Reduction in dendrite formation, and more defined patterns were found. Overall, it was observed that as ethylene glycol increased in weight concentration, viscosity increased, ion conductivity decreased, lower current outputs were observed, and dendrite formation reduced due to a decrease in mass convection.
