Electroplating Quiz

Which of the following is not true about electrodeposition?

• Electrodeposition is a redox reaction.
• In electrodeposition, the metal that is being coated is the anode.
• Electrodeposition is used in engineering and home decoration. 
• Electrodeposition occurs in an electrolytic cell.

Which equation would you use to calculate the cell potential of a redox reaction that is not at STP?

• E_cell = E⁰ - ((RT)/nF)lnQ
• E_cell = E⁰ - (.0591/n)logQ
• E_cell = E⁰ - (.0591/nF)logQ
• E_cell = E⁰ - (.0591/F)lnQ

Why is the solution used in electroplating important? 

• It is what plates the metal.
• It can change the physical properties of the metal that is being put on the cathode.
• It can change the chemical properties of the metal that is being put on the cathode.
• It can coat the cathode with its ions.
