Think about how acids and bases would affect the water quality in the two lakes.
Which set of pH data would you expect to see based on
your observations?
O Lake A: pH = 4.5; Lake B:pH = 7.5
O Lake A: pH = 8.3; Lake B: pH = 3.7
O Lake A: pH = 6.6; Lake B: pH = 6.8
Lake A: pH = 10.2; Lake B:pH = 1.7

3. Lake A: pH = 6.6; Lake B: pH = 6.8

Explanation:

Water quality has greatly affected by the presence of acid and base inside the water. The water is not good for health when its highly acidic or highly basic. If the pH of water is nearly neutral, this water is best for drinking purpose. In the option 3, both lake A and lake B has pH nearly neutral so this water causes no bad effect on the health of the human body. Highly acid water has low water quality due to the presence of metals which adversely affect our body.

yes it is   dangerous

explanation:

because that foot is discusting and could get you sick
