Which statement best describes the difference between a substance with a pH of 2.0 versus a substance with a pH of 4.0? a
(1 point)
O The substance with a pH of 2.0 would have 100 times as many hydrogen ions per volume of water.
o The substance with a pH of 4.0 would have 100 times as many hydrogen ions per volume of water.
O The substance with a pH of 4.0 would have twice as many hydrogen ions per volume of water.
O The substance with a pH of 2.0 would have twice as many hydrogen ions per volume of water.

The answer is the first one.

Explanation:

The lower a pH level the higher the the number hydrogen ions present in the acid's container.

ph = - log(H)

4 = - log(H)

- 4 = log(h)

10^-4 = H+

1 * 10^-4 = H +

ph = - log(H)

ph = 2

- 2 = log(H)

10^-2 = H

1*10^-2 = h

Something the power - 2 is 100 times greater than something with the power of -4

answer; i believe that the correct answer is (a) potassium(k)

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )
