Question

Calculate the pOH of this solution. pH = 1.90 pOH =

Answer 1

12.10

Step-by-step explanation:

Answer 2

12.1

Step-by-step explanation:

Since the pH has been given, the pOH can be found by using the formula

pH + pOH = 14

pOH = 14 - pH

From the question we have

pOH = 14 - 1.9

We have the final answer as

12.1
