What's in the Bottle Post Lab Analysis Questions

1) What type of bond was found in each unknown? What experiments and properties helped you determine each type of bond?

2) What tests were most influential in your identification of the bond types?

3)How do the melting points of ionic compounds compare to covalent compounds? What evidence from the investigation supports your conclusion?

4) When the solids were placed in water were all the results the same? What types of solids conduct electricity in water? Use your investigations to explain what happened.

5) If the solid is ionic, explain why you cannot make the general statement that “all ionic compounds are soluble in water.” What evidence from the investigation supports your conclusions?

6) Why was it necessary to use distilled water and not tap water?

7) Wax is a saturated hydrocarbon, a covalent compound. Wax is not soluble in water yet sugar is also a covalent compound and is soluble in water. Look at the structure of both compounds and explain what could justify these results.
