Pure water with no ions in it at all, which is very hard to get outside of the chem lab, does not conduct electricity. From random googling: Pure water has a very high resistivity, but it is finite.

This includes carbon dioxide, which dissolves to form carbonic acid, and dissociates to form charge carriers. There ...
