Answer:

1.62x10⁻¹² M

Explanation:

HClO₃ is a strong acid, meaning that a 6.2x10⁻³ M solution has a molar concentration of H⁺ of 6.2x10⁻³.

With the above information in mind, we can calculate the pH of the solution:

  • pH = -log(6.2x10⁻³) = 2.21

Now we can calculate the pOH of the solution, using the pH:

  • pOH = 14 - pH
  • pOH = 11.79

Finally we calculate [OH⁻], using the definition of pOH:

  • pOH = -log[OH⁻]
  • [OH⁻] = [tex]10^{-pOH}[/tex] = 1.62x10⁻¹² M
