Disscussion Points
After watching the animation about the process of dissolving, answer these questions:
1) What are the forces that are holding the particles of a salt crystal together?
2) How do water molecules disturb the attractive forces in the salt crystal? Would stirring affect this?
3) Why is water a great solvent?
4) Vegetable oil is made of carbon and hydrogen atoms bonded together in long chains. There is very little charge in these type of molecules. Would water dissolve vegetable oil? Why or why not?
