Here's the breakdown:

* pH is a measure of the acidity or alkalinity of a solution.

* pH scale ranges from 0 to 14.

* Lower pH values indicate a higher concentration of hydrogen ions (H+), which are also known as protons.

* Higher pH values indicate a lower concentration of hydrogen ions (H+).

Therefore, a lower pH means a higher proton concentration.

Think of it this way: a solution with a pH of 1 is extremely acidic because it has a very high concentration of protons. As the pH increases, the concentration of protons decreases, making the solution less acidic and more alkaline.
