Final answer:
The anode heel effect wasn't directly addressed but is related to processes at the anode in electrochemical cells. The Standard Hydrogen Electrode (SHE) is used as a reference for measuring potentials in these cells, with zinc oxidation at the anode cited as an example.
Step-by-step explanation:
The anode heel effect is a concept that is not directly discussed in the information provided. However, judging from the context of the cell reactions and galvanic cells, we can infer that the question pertains to the processes occurring at the anode in electrochemical cells. In a galvanic cell, the anode is the electrode where oxidation takes place. For instance, in the provided example, zinc is oxidized to Zn²⁺ ions at the anode. The Standard Hydrogen Electrode (SHE) is used as a reference in measuring the potential of other electrodes. The SHE has an assigned potential of 0 V, which allows for the determination of electrode potentials for various electrochemical reactions.
It was also mentioned that although the reaction happening at the anode is an oxidation, its potential value is often given as a reduction potential, which in the case of the Zn/Zn²⁺ couple is -0.76 V. This is then negated when considering the oxidation process to give a standard electrode potential of 0.76 V for the oxidation that occurs at the anode. In the case of electroplating, such as the electroplating source shown in the photo from Fstep, the anode typically dissolves into the solution to provide metal ions that are then reduced and deposited onto the cathode.
