  1. Electroplating Battery Electrons Electrons Metal Salt Solution Cathode Anode Zinc Ions Electrons • Electroplating is the process of depositing one metal onto another metal. • Electrons travel from the negative end of the battery through the cathode (penny), through the solution, up through the anode (zinc), and into the positive end of the battery. • The positively charged zinc ions from the solution are attracted to the negatively charged cathode. • These ions attach themselves to the cathode. • More positively charged zinc ions are pulled off the anode to replace the ones now on the cathode. A regular unplated penny A similar penny plated in nickel. Another penny plated in gold

  2. Electroplating Applications • Increase Hardness and Durability • Steel parts like camshafts and crankshafts are chrome plated • Increase Conductivity • Electric train rails are nickel plated • Contacts in electrical circuits are gold plated • Increase Corrosion Resistance • Iron and galvanized steel are zinc plated • Enhance • Jewelry is silver and gold plated Electroplating Factory Copper plated Rose

  3. Electrostatics • Most atoms are neutral because they have the same amount of protons as electrons. • Some electrons can move freely from one atom to another. • Static electricity is the imbalance of positive and negative charges. • Like charges repel, and opposite charges attract each other. • A common way to move electrons from one place to another is to rub two objects together.
