In the investigation "Comparing the Effects of the Products of Cellular Respiration
and Combustion," the gaseous products of cellular respiration and combustion were
bubbled through a solution of bromothymol blue and water. Explain why and what
colour the solution changed to.

Sagot :

The solution changed color because the substances are not neutral.

pH

Chemical substances have different concentrations of the hydrogen cation, called PH.

The higher the pH, the more basic the substance, and the lower the more acidic.

Bromothymol blue is a pH indicator that changes its color according to the pH of the substance, yellow for acid, blue for basic and green for neutral.

In the case of the reactions in question, we have the release of CO2 (acid) in combustion and in cellular respiration, changing the color of bromothymol blue to yellow.
