When the sodium chloride dissolves it forms a solution. The solution contains the water molecules, and the sodium ions and the chloride ions from the sodium chloride. The fast moving water molecules constantly collide with the ions, and crowd around ('solvate') them, so that the ions can not stick together. Silver nitrate is an ionic solid.
