pH is defined as -log[H+]. This means that if one knows the concentration of hydrogen ion in solution, the pH is simply the negative logarithm (base 10) of that. Similarly, one can find the pOH simply by substituting the concentration of OH- for the concentration of H+ in the aforementioned formula.
The measure of the H+ concentration is the pH.
pH is a measure of the acidity of the solution. It describes the concentration of H+ or H3O+ ions in a solution. pH= -log10[H+]. Therefore, the lower the pH, the higher the concentration of hydrogen atoms and the more acidic the solution.
The pH is a measure of the activity of the ion H+ in a solution.
H plus ion concentration can be decreased by adding base to the solution. The reduction can also be done by accepting hydrogen ions.
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
Water
The measure of the H+ concentration is the pH.
pH is a measure of the H+ ion concentration. Therefore if the concentration is 8.6, the pH is 8.6.
