![### Balancing Redox Reactions
**Objective:**
Complete and balance the following redox reaction in acidic solution:
\[ \text{As}(s) + 10 \, \text{H}^+(aq) \rightarrow \text{H}_3\text{AsO}_4(aq) + 5 \, \text{e}^- + 4 \, \text{H}_2\text{O}(l) \]
**Instructions:**
To balance this redox reaction:
1. **Identify Oxidation and Reduction:**
- Determine which elements are oxidized and reduced by checking changes in oxidation states.
2. **Balancing Atoms:**
- Balance the atoms that undergo changes in oxidation state.
- Add water molecules to balance oxygen atoms.
- Add hydrogen ions to balance hydrogen atoms.
3. **Balancing Charge:**
- Balance the charge by adding electrons (e⁻).
4. **Ensure both mass and charge are balanced.**
**Interactive Tools:**
Below the equation, there is a selection of buttons which help in balancing the reaction:
- **Numbers (0-9):** Used for adding numerical coefficients.
- **Charge Indicators (e.g., 1⁻, 2⁺):** Used for indicating charged species.
- **States of Matter:** Indicate whether the substance is solid (s), liquid (l), gas (g), or aqueous (aq).
- **Chemical Species and Ions:** Includes electrons (e⁻), hydronium (H₃O⁺), hydroxide (OH⁻), protons (H⁺), and others.
Use these tools to click and add the necessary components to balance the redox reaction properly in an educational setting.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faeef920a-b7fc-42c4-a405-16f92aebf3b1%2F862f33a4-9173-4bcd-aeeb-b35d6c4d0e28%2Fs0te85_processed.jpeg&w=3840&q=75)
