Meaning and Definition
The concentration of chloride ions in water, especially seawater, usually measured in grams per kilogram of seawater (g/kg).
In oceanography and chemistry, a precise measure of the chloride content used to calculate salinity, assess water mass origins, and study marine ecosystems. It specifically refers to the mass of chloride, bromide, and iodide ions (assuming bromide and iodide are replaced by chloride) per unit mass of seawater.

- Misspelling as 'chlorinaty' or 'chlorinity'.
FAQ
Frequently Asked Questions
No. Salinity is a broader measure of the total dissolved salts. Chlorinity measures specifically the chloride ion content and is used to *calculate* salinity using a standard formula.
Primarily in oceanography, marine chemistry, and environmental hydrology.
While possible, it is rarely the primary metric for freshwater studies, where general chloride concentration or total dissolved solids (TDS) are more common. Chlorinity is a standard parameter for seawater analysis.
Traditionally in parts per thousand (‰) or grams per kilogram (g/kg) of seawater.
The concentration of chloride ions in water, especially seawater, usually measured in grams per kilogram of seawater (g/kg).
Chlorinity is usually technical/scientific in register.
Chlorinity: in British English it is pronounced /klɔːˈrɪnɪti/, and in American English it is pronounced /klɔˈrɪnəti/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'CHLORINE' (the element) + 'ITY' (meaning 'the state of') = the state of how much chlorine (as chloride) is in the water.
Conceptual Metaphor
Chlorinity is the salt's fingerprint in water.
