Question

The two tubes contain bromothymol blue. The lights are on. After 24 hours, what will the color of the water be in tube D?

Answer 1

Answer:

B.Yellow

Explanation:

Blue bromothymol will undergo chemical reactions between its own molecules leading to carbon dioxide. This carbon dioxide can turn blue bromothymol into yellow. Given that the time period provided here is 24 hours therefore, it can be clearly said that the blue bromothymol will turn into yellow after 24 hours due to the molecular reactions among the molecules of bromothymol.
