Answer:
The pOH is 10,6 and it is acidic.
Step-by-step explanation:
POH is a measure of the concentration of OH (hydroxyl) ions in the solution. The sum of pH and pOH is equal to 14 in any aqueous solution.
The pOh is calculated as the difference between 14 and the pH value:
pOH = 14 - pH = 14- 3.4 = 10.6. In this case the solution is acidic ( pH is less than 7,0)
The pH scale ranges from values of 0 to 14 (less than 7.0 is acidic and greater than 7.0 is basic, a pH = 7.0 is neutral)
