[tex]pH = 5.08[/tex]
Step-by-step explanation:
The pH of a solution can be calculated from its hydronium concentration using the equation below:
[tex]pH = -\log [H_3O^+][/tex]
where [tex][H_3O^+][/tex] is the hydronium ion concentration in mol/liter unit. This notation is the same as the more familiar symbol [tex][H^+][/tex] for hydrogen ion concentration. Since the hydronium ion concentration is [tex]8.3×10^{-6}\:\text{mol/L},[/tex] the pH value of the solution is
[tex]pH = -\log (8.3×10^{-6}) = -(5.08) = 5.08[/tex]
This means that the solution is acidic since its pH value is below 7.
