Meaning and Definition
A quantitative chemical analysis method that uses the formation of a colored complex to determine the concentration of a metal ion in solution.
An analytical technique, primarily in chemistry and related fields, where a chelating agent (most commonly EDTA) is used as a titrant to bind to metal ions. The endpoint is detected by a color change from an indicator that also binds to the metal ion but is displaced by the stronger chelating titrant.

Differences
No significant lexical or spelling differences. Pronunciation of 'titration' may vary slightly (see IPA).
Connotations
Identical technical connotations in both varieties.
Frequency
Equally rare outside of chemistry, analytical science, and related engineering or environmental science contexts in both regions.

FAQ
Frequently Asked Questions
Ethylenediaminetetraacetic acid (EDTA) is by far the most common chelating titrant.
No, it is specific to metals that form stable complexes with the chosen chelating agent under the conditions used.
Typically with a metal-ion indicator that changes color when the metal ion is displaced from it by the stronger chelating titrant.
Yes, extensively in water quality analysis (hardness), pharmaceutical manufacturing, food industry, and environmental monitoring.
A quantitative chemical analysis method that uses the formation of a colored complex to determine the concentration of a metal ion in solution.
Complexometric titration is usually formal, technical, academic in register.
Complexometric titration: in British English it is pronounced /ˌkɒm.plek.səʊˈme.trɪk taɪˈtreɪ.ʃən/, and in American English it is pronounced /kɑmˌplek.soʊˈme.trɪk taɪˈtreɪ.ʃən/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: COMPLEX-O-METRIC. You measure (metric) metal ions by making a complex with them.
Conceptual Metaphor
A SECRET HANDHAKE DETECTOR: The indicator has one 'handshake' (color) for the metal. The titrant offers a better, stronger handshake, so the metal lets go of the indicator, causing a visible change (color shift).
