Question

A solid is crystalline, has a high melting point and is water soluble. Describe the nature of the solid.

Answer 1

The given solid is an ionic solid as it shows the characteristics of ionic solids such as:
(1). crystalline structure which implies that the constituent particles are arranged in a definite pattern.
(2). high melting point means that high amount of energy is required to break the lattice of the solid.
(3). water solubility suggests that solid is polar in nature as the water is polar compound and dissolves polar compounds
