What is the difference between pH and hydrogen ion concentration?
The hydrogen ion concentration is the number of moles of
The concentration can range from about
To convert such a wide range of numbers into ones that are easier to visualize, chemists take the negative logarithms of the concentrations.
See What is pH?
This gives numbers ranging from about -1 to +15.
If you know the concentration, you can calculate the pH.
Find the pH of a solution in which
If you know the pH, you can calculate the hydrogen ion concentration.
Calculate the hydrogen ion concentration for a solution with pH 2.30.
