Titration Noun
[ty-tray-shun]
Back
Titration
A laboratory technique used to determine the concentration of a substance by reacting it with a solution of known concentration.
Example: This diagram shows a titration setup, where a solution of known concentration (titrant) is added from a burette to a solution of unknown concentration (analyte).

FLASHCARD QUESTION
Front
Analyte Noun
[an-uh-lyt]
Back
Analyte
The solution of unknown concentration in a titration experiment, which is also known as the titrand.
Example: In a titration, the analyte is the solution in the beaker, which has an unknown concentration that is being measured by adding a titrant.

FLASHCARD QUESTION
Front
Titrant Noun
[ty-trant]
Back
Titrant
The solution of known concentration that is carefully added to the analyte during a titration experiment.
Example: This diagram shows a titrant, the solution of known concentration, being carefully added from a buret to determine the concentration of the analyte below.

FLASHCARD QUESTION
Front
Standard Solution Noun
[stan-derd suh-loo-shun]
Back
Standard Solution
A solution whose concentration is known with high precision, which is often used as the titrant in a titration.
Example: This diagram shows a concentrated 'Stock Solution' (a type of standard solution) being used to create several new solutions with known, decreasing concentrations.

FLASHCARD QUESTION
Front
Equivalence Point Noun
[ih-kwiv-uh-luhns point]
Back
Equivalence Point
The point in a titration where the moles of titrant added are stoichiometrically equal to the moles of analyte present.
Example: This graph shows how pH changes during a titration. The equivalence point is the exact spot on the steep curve where the added base has completely neutralized the acid.

FLASHCARD QUESTION
Front
Endpoint Noun
[end-point]
Back
Endpoint
The point in a titration where a physical change, such as a color change from an indicator, signals reaction completion.
Example: This diagram shows that the endpoint of a titration is the exact point where the solution changes color (to faint pink), signaling the reaction is complete.

FLASHCARD QUESTION
Front
Neutralization Reaction Noun
[noo-truh-luh-zay-shun ree-ak-shun]
Back
Neutralization Reaction
A chemical reaction in which an acid and a base react quantitatively with each other to produce a salt and water.
Example: This diagram shows how an acid (HF) and a base (KOH) react by swapping parts to form water (H₂O) and a salt (KF).
