Aim: What is an electrolytic cell? QQ: Na (s)/Na+ (aq) and Cu (s)/Cu2+ (aq) 1. Write the half reactions for each 2. Label the anode and cathode 3. Provide the balanced redox equation 4. Predict the voltage of the cell Do Now: What is electrolysis? Electrolytic Cell: a cell that requires energy to force a non-spontaneous redox reaction to occur. These cells are used for 3 purposes… Electrolysis of a Fused Salt Anode: 2Cl - 2e- + Cl 2 Cathode: Na + 1e- Na Overall Reaction: 2NaCl 2 Na + Cl 2 Electrolysis of Water Anode: 2O 2- O 2 + 4e- Cathode: 2H + + 2e- H 2 Overall Reaction: 2H 2 O 2H 2 + 2O 2 Electroplating Anode: Ag 0 Ag + + 1e- Cathode: Ag + + 1e- Ag 0 Overall Reaction: Ag + + Ag
