2. For an insoluble compound, how might you prevent formation of precipitate?
3. What conditions can you manipulate to make the precipitate more soluble?
4. Does the size of the crystal affect the solublization process?
5. How do you accurately rule out the presence of alkali metals in solution?
6. Which combinations of ions used do you expect to form insoluble salts? What are their Ksp values?
