Answer :
Given the hydronium ion concentration of the solution, its pOH is 7.0.
Option C)7.0 is the correct answer.
What is pH of solution?
The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration [H+] of the given solution.
From the formular;
pH = -log[ H⁺ ]
Also.
pH + pOH = 14
Given that;
- pH = 7.0
- pOH = ?
pH + pOH = 14
7.0 + pOH = 14
pOH = 14 - 7.0
pOH = 7.0
Therefore, given the hydronium ion concentration of the solution, its pOH is 7.0.
Option C)7.0 is the correct answer.
