Question

The endpoint of a titration is overshot! How will this error affect the reported concentration of vinegar, too high or too low?

Answer 1

The reported concentration of vinegar will be too high than its actual value.

Overshooting the endpoint of a titration means that there is an excess of base in the solution. The concentration will be of the base not of the acid of the vinegar. The excess base will result to a higher pH value than the actual pH value of the solution.

Answer 2

Answer:

The reported concentration of vinegar will be too high.

Explanation:

Titration is an analytical technique by which the concentration of an unknown solution (titrand) can be determined by using a solution of known concentration (titrant).

If during the process of titration, large volume of titrant is added, then the calculated concentration of the titrand will also be high. This is known as endpoint overshot.

This is because in the following equation, the volume of titrant added ( V_{titrant} ) is directly proportional to the concentration of the titrand ( c_{titrand} ).

c_{titrant} V_{titrant} = c_{titrand} V_{titrand}

Therefore, the reported concentration of vinegar i.e. titrand will be greater or too high.
