Bromthymol blue is an indicator for acids and bases. This means the indicator will change color based upon whether a solution is acidic (greater concentration of H+ ions) or basic (lower concentration of H+ ions). Bromthymol blue is green at pHs between 6.0-7.6. Bromthymol blue yellow at pHs below 6.0 and blue at pHs above 7.6.
