Question

What is the pOH of a KOH solution that has [OH− ] = 5.81 × 10−3 M?

Answer 1

2.24

Step-by-step explanation:

Answer 2

The pOH of the KOH solution is 2, 24.

Step-by-step explanation:

The pOH is a measure of the concentration of OH (hydroxyl) ions in the solution.

The pOH is calculated as :

pOH = -log (OH-)= -log ( 5.81 × 10−3 M)= 2,24.
