Question

cristina is performing an experiment on photosynthesis. she is trying to determine if photosynthesis will take place under varied conditions. cristina uses bromothymol blue to aid her conclusion. why would using bromothymol blue be helpful? bromothymol blue can be used to determine if the chlorophyll in plants are active. bromothymol blue is a ph indicator that can reveal if there is a high level of carbon dioxide. bromothymol blue can be used as a source of blue light in her solution. bromothymol blue can be used to determine the amount of sugar concentration in a soltuon.

Explanation:

Bromothymol blue es un indicador de pH que cambia de color en presencia de diferentes concentraciones de dióxido de carbono. En la fotosíntesis, las plantas absorben dióxido de carbono. Si la concentración de dióxido de carbono disminuye (debido a la fotosíntesis), el pH del medio cambiará y bromothymol blue mostrará un color diferente. Esto ayuda a determinar si la fotosíntesis está ocurriendo (ya que la absorción de dióxido de carbono es un paso clave en el proceso).

Answer:

Bromothymol blue is a pH indicator that can reveal if there is a high level of carbon dioxide.
