To find the pH of a solution with a [H+] of 6.8 x 10^-9 M, plug this value into the equation:
pH = -log(6.8 x 10^-9)
pH = -log(6.8) + log(10^-9)
pH = -0.8325 - 9
pH = 8.17
Therefore, the pH of the solution with a [H+] of 6.8 x 10^-9 M is 8.17.
The correct answer is C. 8.17.
Using the equation [H+]= -log[H+], what is the pH of a solution with a [H+] of 6.8 x 10-9 M.
A. 9.99
B. 8.62
C. 8.17
