Question

12. If a solution has a pH of 3, what would the pOH value of that solution be? *

Answer 1

Answer:

The correct answer is pOH= 11

Explanation:

From the aqueous acid-base equilibrium we know that

pH + pOH = 14

If we know pH, we can calculate pOH as follows:

pOH = 14 - pH

In this problem, the solution has a pH of 3, so:

pOH = 14 - 3 = 11

Answer 2

Answer:

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
