Web21 Nov 2013 · Bromothymol blue is an indicator used to detect weak acids and bases. In acidic solutions, it appears yellow, in basic solutions it is blue, and in mid pH ranges, it is green. By determining the absorbance values of solutions at all of these extremes, the equilibrium constant (K c) of this indicator can be calculated. Web1 Jan 2003 · Bromocresol green and bromocresol purple were used for the serum albumin determination [10] and bromothymol blue has been proposed for the determination of serum albumin [11]. Recently, spot test ...

Bromothymol blue may be used for observing photosynthetic activities, or as a respiratory indicator (turns yellow as CO2 is added). A common demonstration of BTB's pH indicator properties involves exhaling through a tube into a neutral solution of BTB. As CO2 is absorbed from the breath into the solution, forming carbonic acid, the solution changes color from green to yellow. Thus, BTB is c…
WebFor a strong acid-strong base titration, the equivalence point is at pH 7. The pH range of phenolphthalein is about 8.3 to 10.0, but the titration curve is so steep at the equivalence point that phenolphthalein makes a good indicator. For a strong base-weak acid titration, the equivalence point is probably near pH 9. theo sharpe julia quinnWebBromothymol Blue.
