Alina Hayes · Answer 1

The Hydrogen ion concentration of a pH 3.8 solution would be higher than that of a solution with a pH of 6.2. This is because since the pH scale measures the concentration of Hydrogen ions. We know that a pH range of less than 7 is considered acidic and greater than 7 is basic. If a solution is more acidic it would possess more hydrogen ions than if it weren't. In this case a pH value of 3.8 is more acidic than pH 6.2.

Regan · Answer 2

PH = - [H+]. So, when the concentration of the hydrogen ions increases, the pH decreases and vice versa. Therefore, the concentration of hydrogen ions is higher in pH 3.8.
