Chapter 17, Problem 32E

(a)

Interpretation Introduction

Interpretation: The ion between ${\text{Na}}^{+}\text{or}{\text{Mg}}^{2+}$ which is expected to be more strongly hydrated needs to be determined.

Concept Introduction : Solute interacts with solvent molecules to form a solution. Many liquids are used as solvents and among them water is the most common solvent. When water is used as solvent, the dissolving process is called hydration. Tendency of hydration depends on the atomic size. Increasing atomic size causes increase of ionic radius increases resulting decrease in hydration.
