Answer:
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.
