Pre-Lab Questions:
1. Why does
the light bulb light up? What does it mean if the light bulb doesn’t light?
2. Why did we
add nothing to a beaker of water and test it?
Questions:
4. How are the
compounds similar that caused the bulb to light?
5. True or
false: The reason a compound did not cause the bulb to light is because the
substance did not dissolve in water. Explain your answer.
6. What could
cause a false reading or incorrect reading (light bulb lights up when it
shouldn’t) in the laboratory?
