Definition

Noun: 1. The concentration of a solution as determined by titration: In chemistry, the "titre" (also spelled "titer") is the measured value that expresses the concentration of a substance in a solution. It is found by performing a titration, a laboratory method where a solution of known concentration is used to determine the concentration of an unknown solution. 2. A standard of strength or purity: More generally, it can refer to the strength, potency, or concentration of a substance, such as an antibody in a serum, a virus in a vaccine, or a chemical in a solution.

Usage Examples

• Noun:
  • The titre of the acid solution was calculated to be 0.1 mol/L.
  • A high antibody titre in the blood sample indicates a strong immune response to the infection.
  • The lab report listed the titre of the reagent for quality control purposes.

Advanced Usage

• "To have a high/low titre": This phrase is commonly used in medical and biological contexts to describe the measured concentration level of a specific component.
  • Patients recovering from the illness typically have a high antibody titre.

Variants and Related Words

• Titer (noun): This is the standard American English spelling of "titre". The meanings are identical.
• Titration (noun): The laboratory process or technique used to determine the titre.
  • Performing an accurate titration is essential for finding the correct titre.
• Titrate (verb): To perform the process of titration.
  • The chemist will titrate the sample to ascertain its titre.

Synonyms

• Concentration: The amount of a substance per defined space.
• Strength: The potency or intensity of a solution or substance.
• Potency: The power or effectiveness of a substance.

Notes on Usage

• Spelling: The spelling "titre" is primarily used in British English and in scientific contexts influenced by it. The spelling "titer" is standard in American English. Both are correct and refer to the same concept.
• Context: This word is highly specialized and is almost exclusively used in scientific, medical, and laboratory settings (e.g., chemistry, immunology, virology). It is not commonly used in everyday conversation.
