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

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.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
