Answer:
11.76
Explanation:
Potassium hydroxide is a strong base that dissociates completely according to the following reaction.
KOH(aq) → K⁺ + OH⁻
Then, the concentration of OH⁻ will be 0.00580 M.
The pOH of the solution is:
pOH = -log [OH⁻]
pOH = -log 0.00580 = 2.24
We can calculate the pH using the following expression.
pH + pOH = 14
pH = 14 - pOH = 14 - 2.24 = 11.76
