Using a small-drop microburet, deliver 5 drops of 0.1 M HCl to each of 11 wells of a 1x12 well strip. Add 1 drop of bromothymal blue indicator to each well and stir. Add no NaOH to the first well. Add 1 drop of 0.1 M NaOH to the second well. Add 2 drops of 0.1 M NaOH to the third well. Repeat until 10 drops of NaOH have been added to the eleventh well. Stir the solution in each well. Make sure to wipe the stirrer between wells. The equivalence point occurs at the first well where the color has changed.
