![### Oxidation Half Reaction Balancing in Acidic Solution
**Question:**
When the oxidation half reaction is balanced (for the reaction given below which occurs in acid) using the smallest integer coefficients possible, what is the coefficient of H₂O in the balanced half reaction?
\[ \text{MnO}_4^- + \text{HSO}_3^- \rightarrow \text{MnO}_4^{2-} + \text{SO}_4^{2-} \]
**Options:**
- a. 2
- b. 0
- c. 1
- d. 4
- e. 3
### Explanation:
To answer this question, we need to balance the oxidation half-reaction for the given chemical equation in an acidic solution step-by-step.
1. **Write the unbalanced oxidation half-reaction:**
\[ \text{MnO}_4^- + \text{HSO}_3^- \rightarrow \text{MnO}_4^{2-} + \text{SO}_4^{2-} \]
2. **Separate the reaction into two half-reactions (oxidation and reduction):**
- _Oxidation half-reaction:_
\[ \text{HSO}_3^- \rightarrow \text{SO}_4^{2-} \]
- _Reduction half-reaction:_
\[ \text{MnO}_4^- \rightarrow \text{MnO}_4^{2-} \]
3. **Balance each half-reaction separately:**
- _Balance atoms other than O and H._
- _Balance oxygen atoms by adding H₂O._
- _Balance hydrogen atoms by adding H⁺._
- _Balance the charges by adding electrons (e⁻)._
4. **Combine the half-reactions and ensure electron balancing.**
**Through these steps, you will find the correct coefficient for H₂O.**
### Answer:
After going through the balancing and combination process, the coefficient of H₂O in the balanced half reaction is determined to be **3**.
Therefore, the correct answer is:
- e. 3](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4246633b-29b8-4fd8-93c1-8799be822ca9%2Fa70d60a3-1c04-40e4-8ea7-cf3875f2b469%2F41o77mr_processed.png&w=3840&q=75)
