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.
In molten copper, positively charged copper ions (Cu2+) carry the electric charge as they move towards the negative electrode. Electrons flow through the external circuit from the negative electrode to the positive electrode.
To direct ions in a solution towards a specific direction, an electric field can be applied using electrodes placed in the solution. This method, known as electrophoresis, causes positively charged ions (cations) to move towards the negative electrode and negatively charged ions (anions) to move towards the positive electrode. Additionally, the movement can be influenced by gradients in concentration or pH, which can create diffusion-driven motion.
Ions that conduct electric current are typically charged particles found in electrolytes, such as sodium (Na⁺), potassium (K⁺), calcium (Ca²⁺), chloride (Cl⁻), and sulfate (SO₄²⁻). When dissolved in water or melted, these ions move freely, allowing them to carry electric charge. The movement of positive ions toward the negative electrode and negative ions toward the positive electrode constitutes the flow of electric current in an electrolyte solution.
Cations are positively charged ions that are attracted to the cathode (negative electrode) during electrolysis or in an electrical field. These ions move towards the cathode where they gain electrons to become neutral atoms.
Copper ions will move towards the cathode (negative electrode) and iron ions will move towards the anode (positive electrode) in an electrolytic cell.
Positively charged ions move to the negative electrode in a process known as electrochemical migration due to the attraction between opposite charges. The negative electrode has an excess of electrons, which attract the positively charged ions towards it. This movement is a key mechanism in processes like electrolysis and battery operation.
When current passes through an electrolyte, it causes chemical reactions at the electrodes. Positive ions move towards the negative electrode (cathode) and negative ions move towards the positive electrode (anode). This leads to the conversion of the ions into neutral elements or compounds at the electrodes.

Applying an electric field using electrodes can cause the ions to move towards a specific direction through a process known as electrophoresis. By setting up a voltage gradient, positively charged ions will move towards the negative electrode, while negatively charged ions will migrate towards the positive electrode.
A lithium-ion battery works by moving lithium ions between the positive and negative electrodes, creating a flow of electrical energy. When the battery is charged, lithium ions are stored in the negative electrode. When the battery is discharged, the ions move to the positive electrode, generating electricity.
Chloride ions are negatively charged and are attracted to the positively charged electrode due to electrostatic forces. This attraction causes the chloride ions to move towards the positive electrode during electrolysis.
No, the movement of electrons through the solution is not what causes electrolyte solutions to conduct electricity. Rather, it is the movement of ions (charged particles) within the solution that conducts the electric current.

If you dissolve potassium bromide in water and add electricity, the water will undergo electrolysis. Potassium ions will move towards the negative electrode (cathode), while bromide ions move to the positive electrode (anode). This process will lead to the decomposition of water into hydrogen gas and oxygen gas at the respective electrodes.
When electricity passes through a copper sulfate solution, the copper sulfate dissociates into its ions: Cu2+ and SO4 2-. The Cu2+ ions move towards the cathode (negative electrode) and get reduced to form copper metal while SO4 2- ions move towards the anode (positive electrode) where they may undergo various reactions.
