Difference between solid and liquid NaCl (from chemistry point of view)
Answers
Answer:
In solid Medium
Solid NaCl is a systematic matrix of sodium and chloride ions that remains solid because of the systematic geometric pattern. The ions vibrate, but stay in place.
In liquid Medium
In aqueous solution the sodium ions attract the negative dipole of water molecules and surround themselves with a coating of water. Likewise the chloride ions attract the positive dipole of water molecules and form a coating of water. The ions with their coatings of water drift around in the water.

Answer:
The ions vibrate, but stay in place. As solid sodium chloride is heated the added energy makes the ions to vibrate at greater amplitude. At the melting point, the ions have enough energy to move out of the orderly crystal matrix. ... Thus molten sodium chloride has all the properties of a liquid.
