Answer:

pH = 10

Explanation:

As the problem states, with strong bases the hydroxide ion concentration [OH⁻] is equal to the concentration of the base. That means that in this case:

  • [OH⁻] = 0.0001 M

With [OH⁻] we can calculate the pOH of the solution:

  • pOH = -log[OH⁻]
  • pOH = 4

Then with the pOH, we calculate the pH of the solution:

  • pH = 14 - pOH
  • pH = 10
