Answer:
9
Explanation:
Given parameters:
pH of solution = 5
Unknown;
pOH of the solution = ?
Solution:
The pH scale is a scale that delineates the hydrogen ion concentration of a solution. It marked from 1 to 14.
pH = -log[H⁺]
For any aqueous solution, the sum of the pH and pOH is 14;
pH + pOH = 14
since pH = 5;
pOH = 14 - pH
pOH = 14 -5 = 9
The pOH of the solution is 9.
