The pH of a solution is raised from 3 to 5. Which of the following statement is false?








A. The initial solution could be 0.001 M HNO3.





B. The initial [H+] (at pH = 3) is 10鈥? M.








C. The pOH decreases from 11 to 9.








D. The final [OH鈥揮 (at pH = 5) is 10鈥? M.








E. The [H+] decreases by a factor of 20.The pH of a solution is raised from 3 to 5. Which of the following statement is false?
E is false





at pH = 3 [H+] = 0.0010 M


at pH = 5 [H+]= 0.000010 M





[H+] decreases by a factor of 100
