Draw the diagram of a galvanic cell and indicate the direction of flow of electrons and current for the cell constructed using $Al|Al^{3+}$ and $Ag^{+}|Ag$ half-cells,given $E^o_{Al^{3+}|Al} = -1.66 \ V$ and $E^o_{Ag^{+}|Ag} = 0.80 \ V$.

(N/A) $1$. Identify the anode and cathode based on standard reduction potentials: $E^o_{Al^{3+}|Al} = -1.66 \ V$ (Anode) and $E^o_{Ag^{+}|Ag} = 0.80 \ V$ (Cathode).
$2$. The cell reaction is: $Al(s) + 3Ag^+(aq) \rightarrow Al^{3+}(aq) + 3Ag(s)$.
$3$. In a galvanic cell,electrons flow from the anode ($Al$ electrode) to the cathode ($Ag$ electrode) through the external circuit.
$4$. The conventional current flows in the opposite direction,i.e.,from the cathode ($Ag$ electrode) to the anode ($Al$ electrode).
$5$. Diagram description: An $Al$ electrode is placed in an $Al(NO_3)_3$ solution and an $Ag$ electrode is placed in an $AgNO_3$ solution,connected by a salt bridge and an external wire with a voltmeter.
