Define the equivalence point of a titration.
The equivalence point is the point in a titration when the amount of added titrant is stoichiometrically sufficient to completely consume the analyte.
In an experiment, how would a chemist know they have reached the endpoint of a titration?
A chemist would know the endpoint has been reached by observing a signal, such as a distinct and permanent color change in the analyte solution.
What key assumption is made about the titration reaction for the equivalence point to be valid?
It is assumed that the titration reaction goes to completion.
What is a titrant?
A titrant is a solution of known concentration used in a titration to determine the amount of an analyte.
What is the endpoint of a titration?
The endpoint is an observable signal, such as a color change, which indicates that the equivalence point has been reached.
What is an analyte?
An analyte is the substance whose amount is being determined during a titration.
If you are given a solution of unknown concentration (the analyte), what must you know about the solution in your buret (the titrant) to perform a successful titration?
To perform a successful titration, you must know the precise concentration of the titrant.
What is the primary purpose of a titration?
The purpose of a titration is to use a titrant of known concentration to determine the amount of an analyte.
How are the amounts of titrant and analyte related at the equivalence point?
At the equivalence point, the amount of titrant added is stoichiometrically equivalent to the initial amount of the analyte, meaning the analyte has been completely consumed.
How is the equivalence point related to the endpoint?
The endpoint is the observable signal (e.g., color change) used to approximate the equivalence point, which is the theoretical point of complete reaction.
