Question

What is the pH of an aqueous solution with [H3O+] = 6×10−12 M ?

Answer 1

Answer: pH = 10.92

Explanation:

To determine the pH of an aqueous solution, we use the following mathematical relation; pH = - log [H3O+]

                                           = - log (6 x 10∧ -12)

                                           = 12 - 1.08

                                   pH =  10.92
