2. In titration experiment at 25°C, a total of 30 mL of 0.1 M NaOH was added dropwise to conical flask containing 25 mL of 0.1 M HCI and few drops of an indicator. Calculate the pH of the solution before the addition of NaOH, at half equivalence point and at the final volume of titration. Sketch a graph of pH against the volume of NaOH added. What is an acid-base indicator? By referring to Table 1 below, suggest the most suitable indicator to be used in the titration above and justify your answer. Table 1 Indicator Phenolphthalein Cresol red pH range 8.3-10.0 7.0-8.8 Bromothymol blue 6.0-7.6 Litmus 4.7-83
