chlorination

This term is primarily used in technical, scientific, and municipal contexts. In public health, it refers to the critical safety measure of disinfecting water supplies to prevent waterborne diseases. The tone is objective and clinical, typically appearing in engineering reports, health guidelines, or chemistry textbooks.

In organic chemistry, the term describes a specific reaction mechanism. While the word is a noun describing a process, it is almost always used as an uncountable noun because it refers to a general chemical procedure or a systemic treatment rather than a discrete, countable event.
