Final answer:
The anode in the cell diagram is chromium (Cr), which is placed on the far left of the notation, starting with the solid state (s) followed by its electrolyte, indicating it is the site of oxidation.
Step-by-step explanation:
In cell notation, the anode is the electrode where oxidation occurs, and it is represented on the far left side of cell notation.
For instance, in the cell diagram Cr(s) | 1 M CrC13(aq) || 1 M CuCl2(aq) | Cu(s), chromium (Cr) is the anode material. This cell notation clearly indicates that the anode is the chromium (Cr) and the cathode is the copper (Cu).
By convention, the components are listed from left to right in the following order: anode | anode's electrolyte || cathode's electrolyte | cathode.
Also, where concentrations are known, they are included in the notation, and phase boundaries are marked by vertical lines with the salt bridge indicated by a double vertical line.
