Expert Solution

Step 1

The pH of the solution is the power of protons in the solution. While pOH is related to the basicity of the solution. pOH is calculated by subtracting the pH value from 14. The pH value for acids is in the range 1 to 7, for the base, it is 7 to 14, and 7 is the pH for a neutral solution.
