The pH of a solution is measure of the acidity of a certain solution based from the concentration of the hydrogen ions. It is associated with the hydrogen ion dissolved in the solution. It is expressed as pH = -log [H+]. We calculate the concentration of the hydrogen ions from this expression.
pH = -log [H+]
1.65 = -log [H+]
antilog [- 1.65] = [H+]
[H+] = 10^-1.65
[H+] = 0.0224 M
