Algal phytoplankton are single-celled water organisms that can do photosynthesis like plants.In a lake,summer growth of phytoplankton can change the water pH from pH 7.2 to 6.2.This change indicates all of these except

Question

Quizplus · Accepted Answer

The statement "the water at pH 6.2 has twice the hydrogen concentration as before the phytoplankton growth" is incorrect. In reality, a change in pH from 7.2 to 6.2 represents a tenfold increase in hydrogen concentration (and decrease in hydroxide concentration), according to the pH scale. Therefore, choice C is the only option that is not accurate. The other options correctly explain that the water at pH 6.2 is more acidic than before and that the change represents a shift from a slightly basic to a slightly acidic solution.
