Question: 1 / 400

The term pH is a measurement of the concentration of which ions?

Hydroxide Ions

Carbon Ions

Hydrogen Ions

The term pH specifically refers to the concentration of hydrogen ions (H+) in a solution. It is a logarithmic scale that measures the acidity or alkalinity of a solution based on the amount of free hydrogen ions present. A lower pH value indicates a higher concentration of hydrogen ions and hence greater acidity, while a higher pH value indicates a lower concentration of hydrogen ions, reflecting more alkalinity.

This measurement is crucial in various biological and chemical processes, including those in renal physiology, where maintaining appropriate pH levels is essential for optimal functioning. Understanding pH is particularly important in hemodialysis, where blood composition must be closely monitored and adjusted to ensure patient safety and effective treatment.
