Answer:
By definition, a one "molar" solution of hydrogen ion contains one "mole" of hydrogen ion per liter of solution. Therefore, a solution of 10 pH has 1 x 10‐10 moles of hydrogen ions per liter. Furthermore, a solution of 4 pH has 1 x 10‐4 moles of hydrogen ions per liter, and so on.

Answer:
A change of one pH unit represents a 10‐fold change in concentration of hydrogenion.
Explanation:
In a neutral solution, the [H+] = 1 x 10‐7 mol/L. This represents the pH of 7.
