What does pH measure?

A. The amount of hydrogen ions in a solution.
B. The amount of pressure in a solution.
C. The amount of water in a solution.
D. The amount of electrolyte in a solution.



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.
