Question

What is the pOH of 0.5 M KOH?

Answer 1

pOH = 0.3

Step-by-step explanation:

As KOH is a strong base, the molar concentration of OH⁻ is equal to the molar concentration of the solution. That means that in this case:

• [OH⁻] = 0.5 M

With that information in mind we can calculate the pOH by using the following formula:

• pOH = -log[OH⁻]

• pOH = -log(0.5)

• pOH = 0.3
