5.0 x 10-3 pH = - log [H3O+] [H3O+] = 1 x 10^-pH pH = 2.3 [H3O+] = 1 x 10^(-2.3) = 5 x 10^(-3) M
pH is the -log of the hydrogen ion concentration. So pH=-log[H+]
The pH of a solution with H plus 2.3 10 -3 is 4.64.
[H+] = 10-pH [H+] = 10-2.3 [H+] = 0.005 M

apexvs answer 3.3
In a neutral solution, the H plus is equal to OH-. The pH level in such a solution is usually at 7.

- log(2.3 X 10 -12 ) = 11.6 pH -----------------very little H + concentration in this solution.
solution with [OH-] = 2.5 x 10-9 , A solution with [H+] = 1.2 x 10-4, A solution with pH = 4.5
