When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.
We introduced aqueous solutions, which are any homogeneous mixtures that have water as the solvent. We defined two classes of aqueous solution according to whether they conduct electricity (electrolytes) or do not conduct electricity (non-electrolytes).
