Describe the electrical conductivity of ionic substances in the solid, liquid, and aqueous solution phases.
And if u dont mind could u please answer what properties are associated witih compounds containing hydrogen bonds?

An ionic solid is a rigid crystalline arrangement of negative and positive ions, where the total negative charge is equal to the total positive charge. The ions are not free to move, and there are no free electrons, so the solid does not conduct electricity.
When an ionic solid is melted (and very high temperatures are required!) the ions are free to move in the liquid, and it is able to conduct electricity.
When dissolved in water, the ions are free to move around, and the solution will conduct electricity.
Hydrogen bonds occur between molecules, not within them.
In other words, they don't hold the molecule together, but they will attract molecules to each other.
The attractive forces between the molecules make them harderr to separate. Thus, they tend to have higher melting points and boiling points than similar compounds with no hydrogen bonding.
