@Glasshouse- I thought it would be a good idea for you to have the rest of the solubility rules. These remaining rules are based on positive and negative charge of different compounds, and some of the exceptions pertain to negatively charged ions and ionic compounds.
All compounds containing silver (AG+) are insoluble except for silver nitrate. Lastly, any compounds that contain sodium, potassium, and ammonium ions are soluble. You could have deduced these from the solubility rules that Babalaas provided, but it is a little more helpful if you are given these rules rather than needing to discover them yourself.
I am surprised that you have not found these rules in your chemistry textbook. I would recommend checking the appendix of your text. The appendix often includes important, but hard to remember things like solubility rules or molarities of concentrated acids and bases.
