Draw the titration curve. Find the volume of NaOH added at the end‐point in 2 different ways: a) Plotting the graph of the first derivative = average volume vs ΔpH b) Plotting the graph of the second derivative = average volume of the average from 1st derivative vs ΔΔpH 2) Calculate the concentration of the acetic acid solution
