Based on the definition of logarithms, what is the difference in hydrogen ion concentration between a substance with a pH of 2 and a substance with a pH of 3?
O A substance with a pH of 2 has a 10 times higher concentration of H* than a substance with a pH of 3.
O A substance with a pH of 3 has a 10 times higher concentration of H* than a substance with a pH of 2.
O A substance with a pH of 2 has a 100 times higher concentration of H* ions than a substance with a pH of 3.
O A substance with a pH of 3 has a 100 times higher concentration of Htions than a substance with a pH of 2.

The answer is A

Explanation:

Let's break this down. . .

-The lower the pH, the more acidic.

-So, the pH of 2 is more acidic than 3.

-Then, it's pretty obvious that the concentration with more acidic substance will be greater or higher than the other substance.

- As a result, the concentration of pH 2 will be greater or higher than the concentration of pH 3.

If you want the "mathematical" form then here:

Concentration

A pH of 2 would be 10 to the -2; 10^-2 which will equal 0.01

A pH of 3 would be 10 to the -3; 10^-3 which will equal 0.001

Which one is greater than the other?

A substance with a pH of 2 has a 10 times higher concentration of H* than a  substance with pH of 3.
