4.6 Titration (AP Chemistry)

Front

What is titration?

Back

Titration is a laboratory technique used to determine the concentration of a solute in a solution by adding a titrant of known concentration until the reaction reaches its endpoint.

Front

What is the endpoint in a titration?

Back

The endpoint is the point in a titration at which the reaction is complete, often indicated by a color change due to an indicator.

Front

What is the role of an indicator in titration?

Back

An indicator is a substance that changes color at a specific pH level, signaling the endpoint of the titration.

What is the significance of the volume of titrant used in a titration?

Back

The volume of titrant used helps to determine the concentration of the unknown solution based on the stoichiometry of the reaction.

What is the relationship between moles of acid and moles of base in a neutralization reaction?

Back

In a neutralization reaction, the moles of acid and moles of base are related by the stoichiometric coefficients in the balanced equation.
