Chapter 17, Problem 110QRT

(a)

Interpretation Introduction

Interpretation:

The equilibrium constant $K_{\text{c}}$ for the reaction, $\text{Sn}\left(\text{s}\right)+{\text{Pb}}^{2+}\left(\text{aq}\right)\to \text{Pb}\left(\text{s}\right)+{\text{Sn}}^{2+}\left(\text{aq}\right)$, has to be calculated.

Concept Introduction:

The cell potential of the cell is defined as a potential difference between two electrodes.  Inside a cell, redox reaction takes place which consists of reduction half-reaction and oxidation half-reaction.  The Nernst equation is used to calculate the cell potential.

(b)

Interpretation Introduction

Interpretation:

The equilibrium concentrations of ${\text{Sn}}^{\text{2+}}$ and ${\text{Pb}}^{\text{2+}}$ ions in the solution that contain lead ion concentration $\text{1}\text{.1}\text{M}$ excess, has to be calculated.
