A student was conducting a titration experiment and was asked to calculate the theoretical pH of the solution at various points in the titration curve. In this experiment, the student added 47.812 ml of a 2.765M solution of acetic acid to a 200ml beaker. The student then added 92.1 ml of deionized water and began to stir. Calculate the theoretical pH at the following.
