A) 0.00
B) 0.01
C) 0.30
D) 2.00
E) 3.00
2) If the concentration of OH- in a solution is 3.9 x 10-3, what is the pH of the solution?
A) 2.41
B) 3.00

1) HC ------------> H+ + Cl-
HCl is strong acid so it dissociates completely
[H+] = [HCl] = 0.01 M
pH = - log [H+]
pH = - log[0.01]
pH = 2.0
answer = option D = 2.0
2) pOH = - log [OH-]
pOH = - log [3.9 x 10-3]
pOH = 2.41
pH + pOH = 14
pH = 14 - pOH = 14 - 2.41
pH = 11.59
answer = option E = 11.59
