### Oxidation State and Systematic Naming of Complex Ions

#### Example Assignment:

**Objective:**
- Provide the systematic name for each complex ion.
- Determine and select the correct oxidation number of each metal species in the given complex ions.

---

**Complex Ion: [FeCl4(ox)]3−**

- **Oxidation State of Fe:**
    - Your initial attempt: **+3**
    - Feedback: Incorrect

**Complex Ion: [Cu(OH)(OH2)5]2+**

- **Systematic Name:**
    - Your initial attempt: **pentaaquahydroxo copper (III)**
    - Feedback: Incorrect
    - Correction:
        - Note: The ligand **OH−** should be named as **hydroxido**, not **hydroxo**.
        - Also, remember to add **"ion"** at the end of the complex cation name.

- **Oxidation State of Cu:**
    - Your initial attempt: **+3**
    - Feedback: Incorrect

---

### Corrected Information:

**Tips for Naming and Determining Oxidation States:**

1. **Naming Ligands:**
    - **Aqua** for H₂O  
    - **Hydroxido** for OH− (not hydroxo)

2. **Oxidation States:**
    - Verify the sum of the oxidation states within the complex matches the overall charge of the ion.
   
**Example Correction:**

- The correct systematic naming should follow IUPAC conventions strictly using appropriate ligand names and noting the charge correctly.
- For the [Cu(OH)(OH2)5]2+ complex, the corrected name should be **pentaaquahydroxidocopper(II) ion** to reflect the proper oxidation state and ligand name. 

### Educational Notes:

- **IUPAC Naming Conventions:** Ensure the proper IUPAC name is used for each ligand in the coordination complex.
- **Oxidation State Calculation:** Check to ensure the sum of the oxidation states of the metal and its ligands equals the ion's overall charge.

By adhering to these rules, students can accurately name coordination complexes and determine the correct oxidation states of the metal centers.
