Question

What is uses of bromothymol blue and yellow stripes?

Answer 1

Bromothymol Blue Uses. The main uses of bromothymol blue are for testing pH and for testing photosynthesis and respiration. Bromothymol blue has a blue colorwhen in basic conditions (pH over 7), a green color in neutral conditions (pH of 7), and a yellow color in acidic conditions (pH under 7).

Answer 2

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.
