Final answer:

Solutions with a low concentration of H+ ions are basic. The pH scale is inversely related to H+ ion concentration, resulting in higher pH values for basic solutions.

Step-by-step explanation:

Solutions with a low concentration of hydrogen ions, H+, which indicated by a concentration less than 1 × 10-7 M, have a basic pH value. This is because the pH scale is inversely related to the concentration of hydrogen ions in a solution. Therefore, as the concentration of H+ ions decreases, the pH value increases, and the solution becomes more basic. Conversely, when the concentration of H+ ions is high, the solution is acidic, and when the concentration of H+ is at 1 × 10-7 M, the solution is neutral. Notably, a pH value of 7 is considered neutral (such as that of pure water), while pH values below 7 indicate that a solution is acidic and pH values above 7 represent basic or alkaline solutions.
