Explanation:
To perform calculations involving the pH of a solution, we can use the following logarithmic equation:
pH = - log [H3O+] or pH = - log [H+]
In calculations involving the pH of a solution, we always use logarithm to base 10.
In this case, we have:
[H+] = 4.51 x 10^-4 M
So:
pH = -log 4.51 x 10^-4
pH = 4 - log 4.51
pH = 4 - 0.65
pH = 3.35
Answer: pH = 3.35
