Acid–base titration is a quantitative analytical technique for estimating the concentration of an acid or base by neutralizing it with a known-concentration standard solution (Titrant) of acid/base.
Generally, the standard solution of known concentration which is filled in the burette is added dropwise in the sample solution which is poured into the conical flask. To detect the endpoint an indicator is added that changes the color of the solution. There are four types of acid-base titration, including strong acid-strong base, strong acid-weak base, weak acid-strong base, and weak acid-weak base.
MCQ: What is the main purpose of acid-base titrations?
A: To test if reactants react
B: To test the quality of reactants
C: To calculate the concentration of an unknown analyte
D: To calculate the concentration of known analyte
The correct answer is option C: To calculate the concentration of the unknown analyte.
Acid-base titrations are most commonly used to determine the amount of an unknown acid or base in an analysis. It is also used in pharmaceutical applications, environmental analysis, and quantitative chemical analysis.
