Answer :
When we know that the molarity of the hydronium ion we can determine the pH by the following pH = - log [ H3O + ]
pH = - log 10 ( 7.5 * 10 ∧-9 )
pH = 8.125

Answer:
pH = 8.125
Explanation:
The pH of a solution can be defined as measure or the quantity of hydrogen ion that is present in a solution. The pH of a solution determines how acidic or basic a solution is.
In order to be able to determine the pH of a solution, the molar concentration of the Hydronium ion [H3O+] in the solution must be known.
The pH is then calculated using the formula :
pH = - log [H3O+].
[H3O+] = 7.5 x 10⁻⁹ M
pH = - log[7.5 x 10⁻⁹M]
pH = 8.125
