Why is an ionic solid non-conductive, but conductive in aqueous solution?
Because the ions that constitute ionic compounds are not free to move in the solid state...........
The generic ionic solid is
In certain circumstances, with certain solvents, for instance water, the ionic solid can dissolve to produce
Water is an excellent solvent for solvating ions. However, it does not solvate all ions, and it is not the only solvent available.
