Question

Discuss the results and observations of the data obtained for each acid. Specifically, discuss how the equivalence point volumes obtained from the different graphs compare to each other and to the endpoint volume determined from the indicator color change. Also, comment on why so many different means of determining the endpoint volume are necessary. Under what circumstances would one be better than another? Compare your Ka to that reported in the textbook and discuss any discrepancies

the experiment was titration of HCL and NaOH and then determining the equivalence point and the endpoint using a different method

Analysis of the Acid using Different Methods

Methods	Volume at Equivalence Point	[HCl]
Titration Curve	24.45 mL	0.1017M
First Derivative	24.47 mL	0.1018 M
Second Derivative	24.466 mL	0.1018M
Gran Plot	24.40 mL	0.1015M

Answer 1

VOLUMETRIC TITRATION: The process in which, mixing of a base (titrant usually from burette) to an acid (analyte/taken in a conical flask) in order to find the strenth of an acid at a particular point called neutralization point.

EQUIVALENCE POINT VOLUME: The exact quantity of titrant in ml rquired to neutralize the whole quantity of an acid present in a conical flask, it happens at equivalent point.

END POINT VOLUME: This is point where we can see the titration got finished with the help of color change.

(generally, colorless to pale pink color in acidic medium after addition of base from burette.)

The determination of equivalence point volume can be done by the following graphical titration methods.

please find the attchment below, so you can easily understand how you can find the volume at equivalence point.
