Answer:

  • [tex][H_3O^+] = 1*10^{-4.33} \ M[/tex]
  • [tex][OH^-] = 1*10^{-9.67} \ M[/tex]
  • [tex]pOH = 9.67[/tex]

Explanation:

Given;

pH of the solution = 4.33

H₃O+ is calculated as;

pH = -log[H₃O⁺]

4.33 = -log[H₃O⁺]

-4.33 = log[H₃O⁺]

10⁻⁴°³³ = [H₃O⁺]

[tex]Thus, [H_3O^+] = 1 *10^{-4.33}[/tex] M

[OH⁻] is calculated as;

[H₃O⁺] x [OH⁻] = 10⁻¹⁴

10⁻⁴°³³ x [OH⁻] = 10⁻¹⁴

[tex][OH^-] = \frac{10^{-14}}{10^{-4.33}} = 10^{-9.67}\\\\Thus, [OH^-] = 1*10^{-9.67} \ M[/tex]

pOH of the solution is calculated as;

pOH  +  pH = 14

pOH  + 4.33 = 14

pOH  = 14 - 4.33

pOH = 9.67

Thus, pOH of the solution is 9.67

Summary of the calculation:

  • [tex][H_3O^+] = 1*10^{-4.33} \ M[/tex]
  • [tex][OH^-] = 1*10^{-9.67} \ M[/tex]
  • [tex]pOH = 9.67[/tex]
