Chapter 18, Problem 18.9QP

Interpretation Introduction

Interpretation: Explanation should be drawn for the Daniell cell operation and why the cell emf begins to drop after operation a few minute.

Concept Introduction:

Redox reaction are those in which oxidation number changes.

Half reaction are the separated oxidation and reduction reaction that make up the overall redox reaction.

Redox equation can be balanced via the half –reaction methods, which allows for the addition of ${\text{H}}_{2}O$ to balance O ${\text{H}}^{+}$ to balance H, and ${\text{OH}}^{-}$ for taking place in basic solution.

To show: Relate between the standard reduction potential and the concentration of the ion.
