attached is my complete lab report & solution

Procedure Summary:
1. Trial titration:






10 mL of HC2H3O2 were pipetted into a flask, and 20 mL of distilling water was added there.
Also, few drops of phenolphthalein were added.
The molarity of the NaOH solution records to be 0.3 M, and the initial buret reading is
recorded to be 50 mL.
The NaOH solution was added to the flask in increments of about 1 mL during swirling, and
this trial titration is complete when the addition of about 1 mL causes the color to change
from colorless to pink.
The final buret reading was recorded, and it was subtracted from the initial reading to
obtain the volume required for the approximate endpoint.

2. Extract titrations:





The first three steps of the procedure used for the trial titration were repeated.
1 mL from the volume found in the trial titration was subtracted, and the resulting volume
was rapidly added from the buret to the flask.
Now, the titratio...
