Question

When an ionic compound dissolves in water, the individual ions first leave the crystal lattice and then each ion becomes surrounded by a cluster of polar water molecules. What is the sign of the entropy change for each of these two steps in the dissolving process

Answer 1

The entropy of the process in which the  individual ions first leave the crystal lattice is positive while the entropy of the process whereby the each ion becomes surrounded by a cluster of polar water molecules is negative.

What is entropy?

The term entropy has to do with the degree of disorder in a system. The higher the entropy of the system, the more the disorderliness of the system.

Now, the entropy of the process in which the  individual ions first leave the crystal lattice is positive while the entropy of the process whereby the each ion becomes surrounded by a cluster of polar water molecules is negative.
