A white solid has these properties:
1. The solid is soluble in water.
2. The solid is soluble in chloroform, CHCl₃
3. The pure solid does not conduct electricity.
4. An aqueous solution of the solid conducts electricity.
5. When the solid is melted, the resulting liquid does not conduct electricity.

Based upon this information, this solid would most likely be classified as
A) ionic.
B) metallic.
C) polar covalent.
D) covalent network.

I had thought at first that the answer would be A, but it's C. So then, just to make sure, is A wrong because ice isn't exactly white? and that pure water doesn't really conduct electricity that well? And then aqueous solutions of polar covalent compounds *do* conduct electricity then?

Part about aqueous solution is rather strange, but perhaps I am missing something.

Ionic solids conduct electricity when melted.
