-log(1.2 X 10^-5 M H(+)) = 4.9 pH H(+)
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
-log(9.40 X 10^-4) = 3 pH

- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
pH = -log [H+], so if the [H+] is 2.310 M, the pH = -0.3636
It will increase the pH
