In a water culture experiment, the culture solution in a transparent beaker turned green. What precaution
should have been taken to prevent the culture solution from turning green?

Answer Details

The culture solution turned green due to the growth of algae. Algae can grow in water culture experiments when there is sufficient light and nutrients present in the solution. To prevent the culture solution from turning green, the beaker should have been covered with a dark material or placed in a dark environment to limit the amount of light reaching the solution. This will reduce the amount of light available for the growth of algae. Alternatively, the experiment could have been carried out in a growth chamber where the light intensity and duration can be controlled to prevent excessive growth of algae.
