Question

Ions, when an ionic compound is dissolved in water, can best be described as:
A. Hydrated molecules only
B. Dehydrated ions and molecules
C. Both hydrated molecules and hydrated ions
D. Neither hydrated ions nor hydrated molecules
E. Hydrated ions only

Answer 1

Hint: We know that the ionic compounds are those compounds that are usually made up of ions and give both the charges that are positive and negative.

Complete step by step answer:
As we know that, the ionic compounds are dissolved in water for the reason that the water molecules hydrate their ions. When the ionic compounds dissolve in water, the water molecules stabilize the ions that are generally caused by breaking the ionic bond. They only do this for hydrating the produced ions.
The water is one of the polar molecules. It usually has the permanent dipole moment. The oxygen atom has a partial negative charge, and the hydrogen atom has a partial positive charge. When the ionic constituent is placed in water, then the water molecules appeal to the positive and negative ions of the crystal. The positive ions are covered with oxygen atoms, and they have several water molecules of a positive charge.
Similarly, the negative ions are covered with hydrogen atoms, and they have several water molecules of the negative charge. The water molecules reduce the attractions between the ionic ions. So, the ions are hydrated. The diagram of hydrate ions is given below:

So, the correct answer is “Option E”.

Note:
The ionic compounds are dissolved in water then their ions are hydrated in it. The ionic compounds are water-soluble.
