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.    

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
