Chapter 6, Problem 6L.2AST

Interpretation Introduction

Interpretation:

The cell diagram notation for the cell has to be given.

Concept Introduction:

Cell diagram notation:

The cell diagram notation is a shorthand expression of voltaic or galvanic cells.  The reaction conditions (pressure, temperature, concentration) the anode, the cathode and the electrode components are all described in cell notation.

Example:

The overall reaction of the cell is,

  ${\text{3Pb}}^{\text{2+}}\left(\text{aq}\right)\text{+2Al}\left(\text{s}\right)\stackrel{}{\to }\text{3Pb}\left(\text{s}\right){\text{+2Al}}^{\text{3+}}\left(\text{aq}\right)$

The cell notation is written as $\text{Al}\left(\text{s}\right)|{\text{Al}}^{\text{3+}}\left(\text{aq}\right)\Vert {\text{Pb}}^{\text{2}}{}^{\text{+}}\left(\text{aq}\right)|\text{Pb}\left(\text{s}\right)\text{.}$
