What is the percentage error if the experimental
value is equal to the accepted value?

a low [OH– ] and a high pOH

Explanation:

A solution with high pH will have low concentration and a solution with low pH will have high concentration.

A solution with high pH is more basic  

A solution with low pH is more acidic  

pH and pOH is related by pH + pOH = 14

A solution with high pOH is more acidic  

A solution with low pOH is more basic  

Thus we see pH and pOH are inverse to each other.

So second option a low [OH– ] and a high pOH  is the Answer

That is High []  will be low and this will be high pOH………..Acidic solution.
