Purpose: The purpose of this lab is to demonstrate how to electroplate Zinc onto Plain Carbon Steel using an electrolyte solution and electricity. Plain Carbon Steel is highly susceptible to oxidation and corrosion when it is openly interacting with the environment. By plating Steel with a Zinc coating, which is more electrochemically reactive, the zinc will degrade faster sacrificing itself to corrode before the steel will. The Zinc acts basically as a barrier protecting the steel, this lab shows how zinc can be applied to steel forming this barrier. Results: After five minutes of electroplating a small film of zinc developed on the steel, producing a barrier that would protect the steel from corrosion. This process of electroplating shows how to combat the effects of corrosion which costs extreme amounts of money every year. Questions/Discussion: 1. Estimate the thickness of the zinc coating you electrodeposited.
