Note
A universal indicator is collectively a mixture of indicators which show a colour change in a solution, which interprets how acidic or basic a solution is.
Bromothymol Blue Indicator Solution; Aqueous Bromothymol Blue Indicator Solution: Dissolve 50 mg of bromothymol blue in 4 ml of 0.02 M sodium hydroxide and 20 ml of ethanol (95 percent). After the solution is effected, add sufficient water to produce 100 ml. Complies with the following test.
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.
Bromthymol blue changes color over a pH range from 6.0 (yellow) to 7.6 (blue). It is a good indicator of dissolved carbon dioxide (CO2) and other weakly acidic solutions
