Understanding pH and Hydrogen Ion Concentration
* pH: A measure of the acidity or alkalinity of a solution.
* [H+]: The concentration of hydrogen ions (H+) in a solution.
The Relationship
The pH and [H+] are related by the following equation:
pH = -log[H+]
Solving for [H+]
1. Rearrange the equation:
[H+] = 10^(-pH)
2. Plug in the pH value:
[H+] = 10^(-3)
3. Calculate:
[H+] = 0.001 M (Molar)
Therefore, if the pH is 3, the concentration of hydrogen ions is 0.001 M.
