Once an ionic compound, such as table salt (NaCl), is dissolved in water, the only way to break the attractive force between the sodium ions, chloride ions, and water molecules is to
A. allow time for the salt to settle out of solution.
B. evaporate the water, leaving the ionic compound behind as a precipitate.
C. stir the solution until the attractive forces between the ions and the water molecules are broken.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
