Ionic substances conduct electricity through the migration of ions. Positive ions move toward the negative electrode (cathode), and negative ions move toward the positive electrode (anode). In a solid there is no migration (movement) because the ions are locked together in a crystal lattice, the solid form.

Why ionic crystals don't conduct electricity in the solid state?
In the solid state ionic crystals are not dissociated in ions.
Can diamond conduct electricity at its solid state?
No, diamond is an insulator and does not conduct electricity in its solid state. This is because it does not have free electrons to carry an electric current.
Does calcium nitrate conduct electricity?
Calcium Hydroxide cannot conduct electricity when it is in solid state but it can conduct electricity in aqueous solution state or molten state. This is because it is an ionic compound. Ionic compounds are made of charged ions which are held tightly in solid state but become mobile in molten or aqueous solution state. The movement of these mobile ions between electrodes helps in conducting electricity.
Why will dry sodium chloride not conduct the electric current?
A substance can only conduct electricity if it contains charged particles (electrons or ions) that are free to move around. In solid sodium chloride, there are ions but these ions are locked into the ionic lattice and are unable to move. Ergo, solid sodium chloride is unable to conduct electricity.
Which substance can not conduct electricity?
One substance that cannot conduct electricity is nonmetals in solid state, such as plastic and rubber, as they have very few free electrons available to carry an electric current.
Why ionic crystals don't conduct electricity in the solid state?
In the solid state ionic crystals are not dissociated in ions.
Why do ionic compounds do not conduct electricity in the solid state?
Ionic compounds do not conduct electricity in the solid state because their ions are locked in a fixed position and cannot move to carry an electric current. Without the ability of the ions to move, there is no way for the electrical charge to flow through the solid lattice structure.
Does ionic compounds counduct an electric current in the molten state?
Yes, ionic compounds can conduct electricity in the molten state because the ions are free to move and carry an electric charge. In the molten state, the forces holding the ions in place are weakened, allowing them to move and conduct the electric current.
Why potassium iodide can conduct electricity in the molten state but not in solid state?
Potassium Bromide or KBr is not able to conduct electricity in solid state. It is an ionic compound and its ions are not free to move in the solid state, hence they are not able to conduct electricity. But when they are in aqueous state, they are free to move and thus become able to conduct electricity.
Can water conduct electricity in solid state?
No. Water can only conduct electricity in its liquid state with dissolved ionic solutes.
Can ionic substances conduct electricity when in a solid state?
They are conductive in solution or melted.
Why ionic compounds conduct electricity when they are in molten state?
Ionic compounds conduct electricity when they are in the molten state because the ions are free to move and carry electric charge. In the solid state, the ions are held in fixed positions in the crystal lattice and cannot move to conduct electricity. When the ionic compound is melted, the ions become mobile and can carry an electric current.
Do materials with ionic bonds conduct electricity in a solid and liquid state?
Materials with ionic bonds normally conduct electricity only in a liquid state. However metals, which have what are sometimes called "delocalized" ionic bonds, also conduct electricity in the solid state. It is now customary to consider metallic bonds a separate class from both ionic and covalent bonds.
Do ionic bonds conduct electrical?
Ionic bonding is simply a term referring to the attraction between the charged ions in an ionic compound. For a substance to conduct electricity, it must have free electrons or free ions. In a solid ionic compound, the electrons cannot move freely throughout the solid, but instead, they are restricted to their own ions. Also, the ions are fixed in their own positions, and thus, they too cannot move freely. Therefore, ionic compounds in the solid state do not conduct electricity. However, if this ionic compound was dissolved in water or in molten state, the electrons would still be restricted to their own ions. But now, the ions can move freely. This means that ionic compounds CAN conduct electricity when in solution or when molten, but not in the solid state.
Does calcium bromide conduct electricity?
Yes, calcium bromide in its solid form does not conduct electricity because it is made up of a lattice structure of ions that are held together by strong ionic bonds. However, when dissolved in water or melted, calcium bromide will dissociate into ions and can conduct electricity as ions are free to move and carry an electric current.
Why ionic substances do not conduct electricity as solid but when molten state?
Ionic substances do not conduct electricity as solids because the ions are locked in place and cannot move to carry the electric current. However, when the ionic substance is melted, the ions are free to move and carry the charge, allowing the substance to conduct electricity.
Why do ionic crystals conduct electric current in the solid phase liquid phase or when dissolved in water but do not conduct electric current in the solid plase?
Ionic crystals conduct electricity when dissolved in water or in the liquid phase because the ions are free to move and carry electrical charge. In the solid phase, the ions are locked in place and cannot move freely to conduct electricity. In contrast, metals conduct in the solid phase due to the mobility of free electrons within the metallic lattice.
