Esos iones escurridizos

Si se añade sal (NaCl) al agua hasta forma una solución saturada el volumen del agua disminuirá hasta alrededor del 2%.

"The interaction of the electrostatic field of an ion with water tends to align the dipolar water molecules in the direction of the field. In this way the field tends to disrupt hydrogen bonded structures in liquid water, and to compress the water molecules surrounding an ion. These electrostatic effect give rise to a shrinkage of the water".
