ANSWER:
Solution 101P: Here, we are going to complete the given table.
Step1:
pH is the negative logarithm to base 10 of hydrogen ion concentration whereas pOH is the negative logarithm to base 10 of hydroxyl ion concentration, i.e.,
pOH = - log[OH- ] and pH = - log[H+ ]
And pH + pOH =14
We can distinguish acidic, neutral and basic aqueous solutions by the relative values of their pH
Acidic: pH < 7
Neutral: pH = 7
Basic: pH > 7
