A water molecule can be broken apart by releasing **hydrogen ions (H⁺)** and **hydroxide ions (OH⁻)**. The pH scale measures **the concentration of hydrogen ions in a solution, indicating its acidity or alkalinity**.
The pH scale typically ranges from 0 to 14, where a pH of 7 is considered neutral, values below 7 indicate acidity (higher concentration of H⁺), and values above 7 indicate alkalinity (higher concentration of OH⁻).
