pH means -log10(H+concentration) so pH of a H+ concentration 3.6x10-9 is: pH = -log10(3.6x10-9) ≈ 8.4
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
4.5
-log(9.40 X 10^-4) = 3 pH
pH = -log[H+] (pH equals the negative log of the molar concentration of H+)
