ANSWER- Strong Acid, Weak Base
Explanation- Bromocresol green has a pH range of 3.8 to 5.4 which is an acidic pH range.
So it means that if a strong acid and a weak base are titrated then only its possible to achieve this pH range.

It's a weak acid strong base titration
Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
