Answer:
4.3
Explanation:
Data obtained from the question include:
pH = 9.7
pOH =?
The pH and pOH are related by the following equation:
pH + pOH = 14
With the above equation, we can obtain the pOH as follows:
pH + pOH = 14
9.7 + pOH = 14
Collect like terms
pOH = 14 - 9.7
pOH = 4.3
From the calculation made above, the pOH is 4.3
