A student was assigned to take water samples from a lake near his home. He measured the pH of one of the water samples to be 6.0. Which of the following best describes this sample of water?

Question

a
highly acidic
b
slightly acidic
c
neutral
d
slightly basic
e
highly basic

Answer 1

The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral. A pH below 7 indicates acidity, while a pH above 7 indicates basicity.

Since the student measured the pH of the water sample to be 6.0, which is below 7, the water is considered acidic. However, since it is only slightly below neutral (7.0), it would be best described as "slightly acidic."

Therefore, the best answer is:

b) slightly acidic
