Answer and Explanation:
We need to remember the formulas:
- pOH = -log[OH-]
- pH = -log[H+]
- pH + pOH = 14
When given the concentration of OH-, denoted as [OH-], we can plug that value into the equation pOH = -log[OH-] to find the pOH. Once we have found the pOH, we can then subtract that value from 14 to determine the value of pH.
