Discus, describe and show model examples how water will dissolve covalent metal-metal compounds, and how it will dissolve ionic compounds. Observe the polarity of water, how it surrounds a covalent molecule like sucrose, and carries it into solution. Compare this with ionic solvation. The formula umit must first dissociate into ions which will attract the polar water molecule , allow it to surround each ion, and then casrry it into solution
