Answer :
Final answer:
pH measures the concentration of hydrogen ions in a solution, determining its acidity or basicity.
Explanation:
pH is a measure of the concentration of hydrogen ions in a solution. It indicates the acidity or basicity of a substance, with values ranging from 0 (high acidity) to 14 (high basicity).
The pH scale quantifies the amount of hydrogen ions in a solution. An acidic solution has a low pH value, while a basic solution has a high pH value. pH meters are used to measure the pH of a solution by detecting the concentration of hydrogen ions, providing insights into its chemical properties.
