Answer is: <span>pH of the water is 8.33, this is basic solution (pH is greater than seven).
</span>[H₃O+] = 4.60·10⁻⁹ M; equilibrium concentration of hydronium ion.
pH = -log[H₃<span>O+].
</span>pH = -log(4.60·10⁻⁹ M).
pH = 8.33.
pH (potential of
hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous
solution.
