* Give a chemical equation that indicates how your acid (provide structure) was made soluble in water during the experiment. 

**POST-LAB #3 Extraction**

**Objective:** Complete the extraction process, focusing on recovery percentages for both crude and recrystallized compounds. Attach this report to your data/observations and upload it to EduCAT.

1. **Unknown CODE:** _?_ (Code not provided)

2. **Mass of Unknown Used:** 1.015 g

---

**Neutral Compound:**

- **Amount of Crude Neutral:** 0.446 g
- **Total Amount Recovered:** 0.671 g
- **% Recovery Extraction:** 66%
   - **Calculation:** (0.671 g / 1.015 g) x 100 = 66%

- **Mass of Recrystallized Neutral:** 0.31 g
- **% Recovery Recrystallization:** 69.5%
   - **Calculation:** (0.31 g / 0.446 g) x 100 = 69.5%

- **Neutral Melting Point (m.p.):** 134-137 ºC
- **Literature Melting Point:** 136 ºC
- **Identity of Neutral:** 1,2,4,5-tetrachlorobenzene

---

**Acid Compound:**

- **Amount of Crude Acid:** 0.225 g

- **Mass of Recrystallized Acid:** 0.19 g
- **% Recovery Recrystallization:** 84%
   - **Calculation:** (0.19 g / 0.225 g) x 100 = 84%

- **Acid Melting Point (m.p.):** 110-112.3 ºC
- **Literature Melting Point:** 111-113 ºC
- **Identity of Acid:** m-toluic acid

---

**Chemical Equation Requirement:**

Provide a chemical equation that illustrates how the acid structure was made soluble in water during the extraction process. The structure of m-toluic acid should be depicted.

**Chemical Structure of Acid:**

- The drawing indicates a carboxyl group (COOH) attached to a benzene ring with a methyl (CH₃) group.

**Note:** Ensure your chemical equation clearly represents solubilization during extraction.
