What Is Electrolysis

The video tutorial explains electrolysis, a process where electrical current flows through a conducting liquid or molten compound, causing chemical changes. It uses molten sodium chloride as an example, describing how ions move towards electrodes, leading to chemical reactions. The tutorial also covers the roles of electrodes, the concept of electrolytes, and the movement of electrons in metals. Key terms like cations, anions, anode, and cathode are defined, and the importance of ion concentration and potential difference in electrolysis is highlighted.

What is required for a liquid to conduct electricity?

Explain the role of cations and anions in electrolysis.

What happens to the electrodes when current flows through an electrolyte?

Describe the process that occurs when ions meet the electrodes during electrolysis.
