Why are most solid ionic compounds electrically nonconductive, whereas aqueous solutions of ionic compounds are good conductors

there must be free-moving electrons in a compound to conduct electricity.

in solid ionic compounds, there are no free electrons so it can't conduct electricity.

But in aqueous form the forces of attraction are broken and the ions (cations and anions) are free to move. This means there are free electrons that allow the aqueous compound to conduct electricity.

explanation:

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
