1. why is it that some combinations of ions do not seem to react while others result in precipitate? 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? 7. what are their ksp values?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
