Bromothymol blue breathing experiment
WebAug 15, 2024 · Bromothymol blue is a compound that tests the pH using color changes. It is made in a basic solution. It starts out as blue, thus the name ''blue.'' It changes to yellow in acidic conditions.... 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.
