Hydrogen Ion Concentration
Definition - What does Hydrogen Ion Concentration mean?
Hydrogen Ion Concentration is the composition of hydrogen ions in a solution. The acidic, basic and neutral character of a solution can be found out by the Hydrogen Ion Concentration. In water, the hydrogen and hydroxide ions are equal, and the nature of the solution is neither acidic nor basic; it is said to be neutral. This concentration of a solution can be determined by its pH value. A solution is neutral if it has a pH of 7, whereas a solution with a pH level more than 7 is basic and less than 7 is acidic.
Petropedia explains Hydrogen Ion Concentration
The percentage of hydrogen ions present in a solution describes the Hydrogen Ion Concentration. For example, in water most molecules are extremely stable as H2O. Yet, a little amount of molecules are broken to form hydroxide ions (OH-) and hydrogen ions (H+). The balance of these ions denotes the concentration of hydrogen ions and pH value of water. If the hydrogen ions in the water increase, it becomes acidic and if they decrease the water becomes basic.
The concentration of the hydrogen ions can be measured by titrating a solution of a strong acid whose concentration is known with a solution of strong basic; the concentration of the strong basic solution is known by the presence of background electrode with high concentration. Due to the known concentration, it becomes easy to calculate the concentration of hydrogen ions and then the measured potential can be easily correlated with concentrations.
