The answer is:

pOH = 11

Explanation:

In the study of acid-basic chemistry, pOH is recognized as a measure of the basicity or alkalinity of a solution.

- The pOH can see the amount of concentration of the hydroxyl anions (OH).

The pOH can be found by the pH ratio found in the solution as follows:

                                                  pOH + pH = 14

With this, you can see the level of pOH with respect to the relationship with pH or vice versa.

So, if you have a solution with pH=3

you should solve the equation for pOH:

                                                 pOH = 14 - pH  

                                                 pOH = 14 - 3

                                                 pOH = 11

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
