Electrochemical Cell Lab Report

Purpose: to observe ___________________

Half reactions:
For all six reactions: include which species undergoes oxidation or reduction, which is the oxidizing agent or reducing agent, label the reaction that occurs at the anode and the reaction that occurs at the cathode, show how you get the positive voltage for the spontaneous reactions

Draw one electrochemical cell
Al & Zn

Label all the above on the drawing and show the electron movement and ion movement

Find the % efficiency
(Actual/Theoretical) x 100 =

In the conclusion, state that positive voltage must occur for the reaction to be spontaneous. Include ways to improve your experiment i.e. account for the efficiency.
