is e correct??? Jos The pH of a solution is raised from 3 to 5. Which statement is false? A) The final [OH-] (at pH = 5) is 10-9 M. B) The pOH decreases from 11 to 9. C) The initial solution could be 0.001 M HNO3. D) The initial [H+] (at pH = 3) is 10-3 M. (E) The [H] decreases by a factor of 20.
Question 4 (1 point) If pH = 5, what is POH, (H+) and (OH). Is this acidic or basic? Basic, pOH = 10, [H+] = 10-4 (OH-] =10-10 Basic, pOH = 9 , [H+] = 10-5 (OH'] =10-9 O Acidic, pOH = 9 , (H+) = 10-5 [OH-] =10-9 Acidic, pOH = 5, [H+] = 10-5 [OH-] =10-9 Question 5 (1 point) True or False. The stronger the acid, the weaker the base. True False Question 6 (1 point)
