Explanation

The pH of a solution is a measure of its acidity or basicity. The pH scale ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most basic. A solution with a low pH has a higher concentration of hydrogen ions (H+), which makes it more acidic. Conversely, a solution with a high pH has a lower concentration of hydrogen ions, which makes it more basic.
