Describe how the three indicator solutions worked in the titrations. Which indicator solution is the best for acid-strong base titration? specify color changes and the pH readings where the color changes occurred.

The three indicators are phenolphthalein, bromthymol blue, and methyl orange.

The red graph is with methyl orange.

The orange graph is bromthymol blue.

The blue graph is phenolphthalein.
