A) ph electrode and a reference electrode are placed in the solution and it is titrated wih .1 M NaOH. Data for the titration curve are gathered and plotted. The inflection point of the plot is at 34.6 ml. How many moles of NaOH were used to neutralize the weak acid and how many moles of weak acid were present in the same? what is the molecular mass of this weak acid?

c) assuming that the pH meter is accurately standardized, which of the following three measurements will give the more reliable value for the Ka of this weak acid? 1) at the start of titration 2) at the midpoint of the titration, or 3) at the end point of the titration. explain

E) the pH of the misture was 3.78 when 12.0 mL of NaOH was added. what is the Ka of the weak acid?
