Does an aqueous solution of `Mg^(2+)` ions have larger entropy before or after hydration of the ions?

Explanation

To determine whether an aqueous solution of `Mg^(2+)` ions has larger entropy before or after hydration, we can analyze the behavior of the ions in both states.

### Step-by-Step Solution:

1. **Understanding Entropy**:
- Entropy is a measure of the disorder or randomness in a system. Higher entropy indicates greater disorder and more possible arrangements of particles.

2. **State Before Hydration**:
