The typical numerical range of the pH scale is from 0 to 14. This range indicates how acidic or basic a solution is, where lower values signify more acidic solutions (0 being the most acidic) and higher values indicate more basic or alkaline solutions (14 being the most basic). A pH of 7 is considered neutral, which is the point where the concentrations of hydrogen ions and hydroxide ions are equal, as seen in pure water.

This standard range is widely accepted in chemistry and is used in various fields, including biology, environmental science, and medicine. It reflects the measurement of hydrogen ion concentration in aqueous solutions, which is essential for understanding chemical reactions and biological processes.
