Electrochemical - GCSE Chemistry Definition

The term 'electrochemical' refers to processes that involve the conversion between electrical and chemical energy. In GCSE Chemistry, you'll learn that electrochemical reactions involve the movement of electrons to either generate electricity or cause a chemical change. This process takes place in devices called electrochemical cells. One example is a battery, where chemical reactions inside it create electrical energy to power devices. Electrochemical reactions are also used in electrolysis, where electricity is used to break down molten or dissolved ionic compounds into simpler substances. Understanding these reactions helps us see how chemistry and electricity work together in everyday technology.
