    The answer to your question is pH = 8.5

    Explanation:

    Data

    pH = ?

    [H₃O⁺] = 3.0 x 10⁻⁹ M

    Formula

    pH = - log [H₃O⁺]

    -Substitution

    pH = - log [3.0 x 10⁻⁹]

    -Simplification

    pH = - (-8.523)

    -Result

    pH = 8.523

    -Conclusion

    pH of a solution with a [H₃O⁺] of 3.0 x 10⁻⁹ is 8.5, then it is an alkaline solution.
