How many ozone molecules can each chlorine ion destroy?

Each chlorine ion has the ability to destroy a significant number of ozone molecules due to the nature of the chemical reactions involved. Specifically, one chlorine ion can participate in a chain reaction where it reacts with ozone (O₃) to form oxygen (O₂) while regenerating the chlorine ion, allowing it to continue to react with additional ozone molecules.

Research indicates that a single chlorine atom can effectively break down around 100,000 ozone molecules before it is rendered inactive or removed from the atmosphere. This high activity contributes to the depletion of the ozone layer, which is essential for protecting the Earth from harmful ultraviolet radiation. The ability of chlorine to destroy such a large number of ozone molecules emphasizes the potency of chlorofluorocarbons (CFCs) and other chlorine-containing compounds in ozone destruction.
