Interpretation:
The terms end point and equivalence point has to be distinguished.
Concept-Introduction:
Acid–base titration: It consists of a neutralization reaction where a measured volume of a known concentrated an acid or a base is used for determining the concentration of an unknown solution of base or acid with known volume. The known concentrated solution is called the titrant, while the unknown concentrated solution is called the analyte.
Acid–base indicator: It is a compound used to identify the endpoint in an acid–base titration. Depending on the pH of a solution, these compounds exhibit different colors. Generally, an indicator has a particular color in an acidic solution and another color in basic solution.
Explanation of Solution
Equivalence point is achieved when the exact amount of titrant (known concentration) is added to neutralize the analyte (unknown concentration).
End point: During titration, the end result is viewed by the color change of the analyte with the use of indicator; the end point color change occurs due to the excess amount of titrant added.
