Dear 2E4,

here is your assignment for this holiday. Each person in the group is to find research on the question, give the URL AND summarise what is said in your own words.

__Group 1-2:__ State (just state high or low will do) and explain (why high or low) the melting and boiling points of ionic compounds.

__Group 3-4:__ State and explain the solubility of ionic compounds in water and otrher solvents.

__Group 5-6:__ State and explain the electrical conductivity of ionic compunds in their different states (solid, liquid and gas)
