With reference to the coordination complex ion `[Fe(H_(2)O)_(6)]^(2+)` answer the following: (at. no. of Fe=26)
Give the IUPAC name of the complex ion.

Explanation

To determine the IUPAC name of the coordination complex ion \([Fe(H_2O)_6]^{2+}\), we will follow the systematic naming conventions for coordination compounds. Here’s the step-by-step solution:

### Step 1: Identify the Ligand
The ligand in this complex is water, which is represented as \(H_2O\). In coordination chemistry, water is referred to as "aqua".

**Hint:** Remember that ligands are named before the central metal atom in the IUPAC naming convention.

### Step 2: Determine the Number of Ligands
