WebbTherefore, if we were to change the pH from two to four, we would see the color of the solution go from red to orange to yellow. Now let's see how to choose the right acid-base indicator for a titration. Our goal is to choose an indicator whose color change occurs as close as possible to the pH of the equivalence point.

WebbTools Bromothymol blue (also known as bromothymol sulfone phthalein and BTB) is a pH indicator. It is mostly used in applications that require measuring substances that would have a relatively neutral pH (near 7). A common use is for measuring the presence of carbonic acid in a liquid. WebbAnother frequently used method is the determination of an enzyme reaction detected by an indicator. The most commonly used indicators are pH indicators but there are others such as redox. The simplest system is the detection of fermentation from a certain sugar like dextrose, lactose or other carbohydrates.
