The pH scale is a standard for rating the relative **acidity** and **basicity** of solutions. It is a logarithmic scale that measures the concentration of hydrogen ions (H⁺) in a solution.

1. **Acidity**: A solution with a pH less than 7 is considered acidic, and the acidity increases as the pH value decreases. The lower the pH, the higher the concentration of hydrogen ions.

2. **Basicity**: Conversely, a solution with a pH greater than 7 is considered basic (or alkaline), meaning it has a lower concentration of hydrogen ions. The basicity increases as the pH value increases, with 14 being the maximum pH value for pure water under standard conditions.

While **concentration**, **percent solution**, and **molarity** are related concepts in chemistry, they do not directly relate to the pH scale itself. Therefore, the correct selections are **acidity** and **basicity**.
