**Instructions:**

- Enter electrons as \( \text{e}^- \).
- Use smallest possible integer coefficients.
- If a box is not needed, leave it blank.

A voltaic electrochemical cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge.

\[ 3\text{Mn}(s) + 2\text{Cr}^{3+}(aq) \rightarrow 3\text{Mn}^{2+}(aq) + 2\text{Cr}(s) \]

**What is the reaction that takes place in the anode compartment?**

\[ \text{[Box]} + \text{[Box]} \rightarrow \text{[Box]} + \text{[Box]} \]

**What is the reaction that takes place in the cathode compartment?**

\[ \text{[Box]} + \text{[Box]} \rightarrow \text{[Box]} + \text{[Box]} \]

**In the external circuit, electrons migrate \(\_\_\_\_\_\) the Mn electrode \(\_\_\_\_\_\) the Cr\(^{3+}\) electrode.**

**In the salt bridge, anions migrate \(\_\_\_\_\_\) the Mn compartment \(\_\_\_\_\_\) the Cr\(^{3+}\) compartment.**
