QUESTION:
Determine the pH of each solution and classify it as acidic, basic, or neutral.
(a) pOH = 8.5
(b) pOH = 4.2
(c) pOH = 1.7
(d) pOH = 7.0
ANSWER:
Solution: Here, we are going to determine the pH of the given solution and classify them as acidic, basic or neutral.
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
