Answer:

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
