In a titration involving a weak acid and a strong base, what is the term for the solution of unknown concentration to which another solution is slowly added?
A
Analyte
B
Indicator
C
Titrant
D
Buffer
Verified step by step guidance1
Identify the roles of the solutions in a titration: one solution has an unknown concentration and is being analyzed, while the other is added gradually to react with it.
Understand that the solution with the unknown concentration, to which the other solution is added, is called the analyte.
Recognize that the solution added slowly, usually of known concentration, is called the titrant.
Note that an indicator is a substance used to signal the endpoint of the titration by changing color, not the solution being titrated.
Recall that a buffer is a solution that resists changes in pH, which may form during the titration but is not the term for the unknown solution.
