  2. Electroplating • The process used to cover zinc with copper . Uses direct –current electricity , which causes redox reactions to occur between metal and non metal solution .

  3. Examples • Bumpers on trucks are made of steel . The steel would rust in the snow and rain but manufactures protect it by coating it with nickel and chromium . • Coin would also corrode if they were not coated with nickel • Bikes are also coated to keep from corroding .

  4. Uses of electroplating • Electroplating is used in many industries for function corrosion control or decorative processes . • Used on steel or aluminum parts on light fixtures • Steel bolts and nuts and washers are all coated with zinc . • Electroplating may deposit silver ,copper ,or brass into electrical connectors

  5. Relation • Electroplating can cause redox reaction . Redox reactions are oxidation and reduction reactions • Cations and Anions also have to deal with electroplating . • We learned about oxidation and reduction this year and they both have to deal with electroplating .

  6. Resoures • http://www.engineersedge.com/finishing/electroplating.htm • The book • http://electrochem.cwru.edu/ed/encycl/art-e01-electroplat.htm

  7. Review Questions • What are two examples of electroplating? • What are two examples of uses for electroplating ?
