Answer 2

[H+] = 0.0039 M, where the 3 and the 9 are significant, then pH = 2.41

Answer 3

The pH of any solution is -log [H+]

Therefore pH of your solution is = -log (0.0039)

                                             = 2.409 (correct to 4 significant figures)

Answer 4

pH = -log [H+]

pH = - log 0.0039M

pH = 2.41

Use a scientific calculator to find the result.

Answer 5

-log[0.0039]
