Textbook Problem

When sails of Mg2+, Ca2+, and Be2+ are placed in water, the positive ion is hydrated (as is the negative ion). Which of these three cations is most strongly hydrated? Which one is least strongly hydrated?

Interpretation Introduction

Interpretation:

The most strongly and least strongly hydrated cation has to be determined from the given salt of Mg2+,Ca2+andBe2+

Concept introduction:

There are various kinds of interactions in between atoms, ions and molecules. And the strength of the interaction is related to the size of the ion.

Size of an ion depends on to the charge of the ion. In two types of ions namely anion and cation anion is larger than cation. It is because the gain of an electron which repels other electrons and increases the ionic size.

Explanation

Hydration process is successfully favored for the salts with those which have more interaction with water. And the interaction is closely related to the size of the ion.

Mg2+,Ca2+andBe2+ Ions were produced from the given salts. In these ions Be2+ is smallest one,Ca2+ is the largest one
