**Redox Reactions in Basic Solutions**

1. **Consider this (unbalanced) redox reaction that occurs in a basic solution:**
   
   \[
   \text{ClO}_2^- + \text{N}_2\text{H}_4 \rightarrow \text{NO} + \text{Cl}^-
   \]

   a. **Assign Oxidation Numbers:**
      - Write the correct oxidation number above each element in the equation above.

   b. **Determine Oxidation and Reduction:**
      - Which element is being oxidized in this reaction? ______
      - Which is being reduced? ______

   c. **Identify Agents:**
      - What is the oxidizing agent? ______
      - What is the reducing agent? ______

   d. **Balance the Equation:**
      - Balance this equation using the ion-electron method.

2. **Redox Titration Problem:**

   A redox titration is performed using the reaction from the previous problem. A 50.00-mL basic solution containing \(\text{N}_2\text{H}_4\) is titrated with a 0.144 M solution of \(\text{NaClO}_2\). The titration requires 14.55 mL of the \(\text{NaClO}_2\) solution to convert all of the \(\text{N}_2\text{H}_4\) into \(\text{NO}\). What was the molarity of the original \(\text{N}_2\text{H}_4\) solution?
