Learning objectives

This module is concerned with the dissolving of ionic solids (such as NaCl) in water. 

Having viewed the animations of the dissolving process and completed the questions about these you should be able to 
 

• describe how the interaction of water molecules with ions in the lattice of an ionic solid may cause the solid to dissolve
   
• identify the nature of the ions in the resulting aqueous solution
   
• identify the orientation of the water molecules surrounding a cation and an anion in the solution and explain why these differences
