Question:

A scientist conducts an experiment to see if acids affect the health of a particular type of plant. Three sets of plants were treated with acidic solutions of a pH of 2, pH of 4, and a pH of 6, while the control set was treated with a solution of neutral pH 7.
Results of the experiment:
Plants treated with a pH (2) - 10 of 10 plants are dead
Plants treated with a pH (4) - 5 of 10 plants are dead
Plants treated with a ph (6) - 2 of 10 plants are dead
Plants treated with a ph (7) - 0 of 10 plants are dead
Which is the best conclusion for this experiment?

A High acidity is harmful to this type of plant.
Explaination

High acidity is harmful to this type of plant. The 10 of 10 plants treated with an acidic solution of a pH of 2 were dead. You might or might not know a strong acid has a pH of about zero to 3. However, you could guess it based on the result of this experiment: 10 of 10 plants treated with an acidic solution of a pH of 2 were dead
