Examples
By Part of Speech
verb
British English
- The chemist will titrate the acid solution against a standard alkali.
- We must titrate the drug dosage upwards over several weeks.
American English
- The lab technician titrated the sample to determine its chloride concentration.
- Doctors titrate the medication to achieve the desired therapeutic effect.
adverb
British English
- The drug was administered titrately to avoid side effects. (Note: This form is extremely rare and non-standard; 'in a titrated manner' is preferred.)
American English
- The process was performed titrately. (Note: As above, this form is not standard usage.)
adjective
British English
- The titrate analysis provided the definitive result. (Note: 'titrated' is more common as an adjective, e.g., 'a titrated solution')
American English
- A titrate endpoint was reached after adding 25 ml of reagent. (Note: 'titration' is the noun form used attributively, e.g., 'titration endpoint')
Examples
By CEFR Level

Common Pitfalls
Translation Traps (for Russian speakers)
- Not a direct translation of 'титровать' in all contexts.
- Avoid confusing with 'титрировать' (which is the direct cognate but less common).
- The general sense of 'adjust slowly' is a secondary, metaphorical extension in English.
Common Mistakes
- Using it as a synonym for 'test' or 'try' without the connotation of incremental measurement.
- Misspelling as 'titirate' or 'tittrate'.
- Using it in informal contexts where it sounds jarringly technical.

FAQ
Frequently Asked Questions
No, its primary use is in chemistry and analytical science, but it is also common in medicine and pharmacology (e.g., titrating a drug dose). Metaphorical use in business or general language is possible but rare.
The noun form is 'titration'. For example, 'Performing a titration revealed the concentration.'
Rarely. It is almost always a transitive verb (e.g., titrate something). An intransitive use might be 'The solution is titrating,' but this is highly technical and uncommon.
'Titrate' specifically involves a measured, stepwise addition to find an endpoint in a reaction. 'Calibrate' is broader, meaning to set or correct a measuring instrument against a standard. You might calibrate a pipette before using it to titrate a solution.
