Answer:

The answer to your question is pOH = 3.0

Explanation:

Data

pOH = 0.0010 M

Formula

pOH = -log [OH⁻]

pOH is the measure of the concentration of OH⁻ of a solution. It measures the alkalinity of a solution.

-Substitution

pOH = -log [0.0010]

-Simplification

pOH = -(-3)

-Result

pOH = 3

-Conclusion

The pOH of a solution 0.0010 M is 3.
