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. It is typically sold in solid form as the sodium salt of the acid indicator. WebbpH Indicator Ranges (Ascending pH) Acid-base pH indicators are solutions that have a characteristic color at certain pH levels. They are used to visually signal the acidity or alkalinity of an aqueous (water-based) solution. pH indicators generally change color over a range of two pH units.
