The Solvent Properties of Water Analysis Questions

1. Determine the differences in electronegativities, draw the structural formulas for all the substances, and determine if the bonds are ionic, polar covalent or nonpolar covalent.

 

 

2. Polar and ionic substances generally dissolve in water, nonpolar substances do not. Explain.

 

 

3. Based on the fact that calcium carbonate is an ionic compound, you may be puzzled by your experimental results for this compound. Propose an explanation for the solubility of calcium carbonate.

 

 

4. What basis can you use to decide whether the liquids tested are polar or nonpolar? Which of the liquids tested are polar? Which are nonpolar?
