the molarity of NaOH through separate trials using bromothymol blue as the indicator. It was expected for the results to conclude that the molarity of NaOH is 0.50M. For trial 1‚ 0.50M of NaOH was calculated‚ in trial 2 it was a 0.28M of NaOH and trial 3’s results concluded with 0.54M of NaOH. The results of trial 1 and 3 resemble the most similar and consistent to the expected results of the experiment.
