o
a. sodium nitrate in water
o
b. hydrogen chloride in water
c. acetic acid in water
d. iodine in hexane

A solution with electrolytes will contain ions therefore a solution with a nonelectrical should not contain ions. Iodine I₂  and hexane are nonpolar molecules which contain covalent bonds, so in this case there are no ions in solution.  

Iodine in hexane

Explanation:

An electrolyte is a solution that decomposes upon passage of direct current. An electrolyte must contain ions that dissociate under the influence of external direct current. Solution of ionic substances in polar solvents produce good electrolytes such as a solution of NaCl in water. However, a solution of a nonpolar substance such as iodine in a nonpolar solvent such as hexane is not an not electrolyte. Such solutions contain no ions and do not interact with direct current.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
