During electrolysis, what is the movement of ions in an electrolyte influenced by?

• A. Magnetic fields
• B. Electric current
• C. Thermal energy
• D. Pressure changes

Answer: (B)

The movement of ions in an electrolyte during electrolysis is primarily influenced by electric current. Electrolysis involves the decomposition of a compound into its constituent elements or ions when an electric current passes through it. The electric current creates an electric field that drives the ions toward the electrodes—positive ions (cations) migrate toward the negative electrode (cathode), while negative ions (anions) move toward the positive electrode (anode). This movement is crucial for the electrochemical reactions that take place at the electrodes. Other factors, like thermal energy and pressure changes, do not predominantly direct ion movement during electrolysis. While they can affect the physical properties of the electrolyte (e.g., temperature may increase ion mobility), the fundamental driving force for the migration of ions is the electric current. Magnetic fields can have an impact on charged particles in motion, but in standard electrolysis processes, the primary influence remains the electric potential difference applied across the electrodes.
