Fundamentals of Analytical Chemistry: Titrations in Analytical Chemistry

These flashcards cover the key concepts related to titrations in analytical chemistry, including definitions, procedures, and important terminology.

An analyte in volumetric titrations is determined using __.

volumetric measurements of a standard solution.

In gravimetric titrations, the __ of the reagent is measured instead of its volume.

mass

A __ is a reagent of known concentration used in titrations.

standard solution

Back-titration is used when the reaction rate is __.

slow

The difference between the endpoint and the __ point in a titration is known as titration error.

equivalence

__ produce observable physical changes that indicate completion of a titration.

Indicators

Primary standards must exhibit high purity, atmospheric stability, and __ of hydrate water.

absence

The ideal standard solution for titrimetric methods should undergo __ reactions with the analyte.

selective

A titrant that is standardized is called a __ standard solution.

secondary

The concentration for standard solutions in titrations is commonly expressed in __ concentration.

molar

A standard solution's concentration can be established through direct methods or __.

standardization

In a titration process, the __ point is reached when the amount of added reagent is equivalent to the analyte.

equivalence

__ titrations involve reactions that entail electron transfer.

Redox

In coulometric titrations, the quantity of __ is measured to complete a reaction with the analyte.

charge

A __ by definition has its purity determined by chemical analysis.

secondary standard

millimoles

Titration curves plot a concentration-related variable against __ volume.

titrant

The endpoint of a titration may be indicated by a change in __ of an electrode.
