Find the pH and pOH of solutions with the following [H+];classify each as acidic or basic

a) [H+]=1.0M
b) [H+]=6.8x10^-8M

a) The soln. is highly acidic and pH= - log[H+] = - log [1.0] = 0 ( pH is zero) and pOH = 14.0

b) The soln. is basic and pH = - log [H+] = - log [ 6.8 x 10^-8] = - [- 8 + 0.8325] = 7.1675 and pOH = 6.8325
