Give the characteristics of salts.

Salts:

• Water molecules are polarised, with a negative (oxygen) and a positive side (hydrogen).
• The ionic connections that hold the sodium and chlorine in the salt together are broken by polarised water.
• When the water evaporates, the two elements recombine to create crystals.

Characteristics of salts:

• The salt crystals dissolve in water.
• Salt crystallises into a white powder.
• In the isometric system, the salt crystallises into cubes.
