Question
**Electrochemical Reactions in a Tin-Silver Cell**

In this exercise, we will write the half-reactions for each electrode and the net cell reaction for an electrochemical cell containing tin and silver. The cell notation is as follows:

\[ \text{Sn(s)} \lvert \text{Sn}^{2+}(\text{aq}) \parallel \text{Ag}^{+}(\text{aq)} \lvert \text{Ag(s)} \]

**Anode Reaction:**

At the anode, oxidation occurs. The half-reaction is:

\[ \text{Sn(s)} \rightarrow \text{Sn}^{2+}(\text{aq}) + 2\text{e}^- \]

**Cathode Reaction:**

At the cathode, reduction happens. The half-reaction is:

\[ \text{Ag}^{+}(\text{aq}) + \text{e}^- \rightarrow \text{Ag(s)} \]

**Net Cell Reaction:**

Combining the half-reactions, the net cell reaction is:

\[ \text{Sn(s)} + 2\text{Ag}^{+}(\text{aq}) \rightarrow \text{Sn}^{2+}(\text{aq}) + 2\text{Ag(s)} \]

This shows the overall electron transfer and species involved.
