The question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: Charge on the complex of ferric ion with EDTA is minus one.
Reason: EDTA is a hexadentate ligand.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Explanation

To solve the question regarding the assertion and reason statements, we will analyze both the assertion and the reason step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the charge on the complex of the ferric ion (Fe³⁺) with EDTA is -1.
- To evaluate this, we need to know the charge of the ferric ion and the charge of the EDTA ligand.

2. **Charge of Ferric Ion**:
- The ferric ion (Fe³⁺) has a charge of +3.

3. **Understanding EDTA**:
- EDTA (ethylenediaminetetraacetic acid) is a hexadentate ligand, meaning it can form six bonds with a metal ion.
- The overall charge of the EDTA ligand is -4 because it can donate four acetate groups (each contributing -1 charge) and two nitrogen atoms (which do not contribute to the charge).

4. **Calculating the Charge of the Complex**:
- When the ferric ion (Fe³⁺) binds with EDTA (EDTA⁴⁻), the overall charge of the complex can be calculated as follows:
\[ \text{Charge of complex} = \text{Charge of Fe} + \text{Charge of EDTA} = (+3) + (-4) = -1 \]
- Therefore, the assertion that the charge on the complex is -1 is correct.

5. **Understanding the Reason**:
- The reason states that EDTA is a hexadentate ligand.
- This is also true, as EDTA can indeed bind to a metal ion at six coordination sites.

6. **Evaluating the Relationship Between Assertion and Reason**:
- While both the assertion and the reason are true, the reason does not explain why the charge of the complex is -1. The charge calculation is based on the specific charges of the ferric ion and the EDTA ligand, not solely on the fact that EDTA is hexadentate.

### Conclusion:
- Both the assertion and the reason are true, but the reason is not the correct explanation for the assertion. Therefore, the correct response is:
**Assertion is true, Reason is true, but Reason is not the correct explanation of Assertion.**
