Chapter 17, Problem 17.47SP

(a)

Interpretation Introduction

Interpretation:

The balanced equations for the electrode and overall cell have to be written.  The experiment set up along with labelled electrode and direction of flow of electron and ion has to be sketched.

Concept Introduction:

Shorthand notation is used for describing the voltaic cell which gives simple idea about the cell and the reactions occurred in the electrodes in the cell.

Shorthand notation of Zn/Cu cell is,

$Zn|Z{n}^{2+}\Vert C{u}^{2+}|Cu$

The | notation indicates a phase boundary where the electrode and electrolyte are in physical contact.

The || notation indicates the salt bridge.

If additional reactants are required or specific products are formed, they are written with the solution separated by a comma or a semicolon.

Oxidation: Losing electrons and this process is occurred in anode.

Reduction: Gaining electron, this process is occurred in cathode.
