Chapter 19, Problem 19.53QP

Interpretation Introduction

Interpretation:

The overall reaction for the given voltaic cell should be written.

Concept introduction:

Representation of an electrochemical Cell:

Representation of an electrochemical Cell was recommended by IUPAC at 1953 and they are Zinc-Copper cell.

A phase boundary between metal electrode and ion solution (electrolyte) are represented by a single vertical line (|).

A double vertical line (||) represents the salt bridge between two half cells.

Left side of the double vertical line (||), the anodic half cell reaction would be written and oxidation occurs at that electrode.

Right side of the double vertical line (||), the cathode half cell reaction would be written and reduction occurs at that electrode.

If inert electrode is used it is noted in single vertical line in beside of electrolyte.

The concentrations of electrolytes are mentions right beside of ions in cell notation.

The electron flow is from anode to cathode in the outer circuit.
