Based on log rules and the way pH is calculated, what is the difference in [OH- ]
concentration between point A and point B.
(A)101
(B)105
(C)106
(D)107 - ANS-(C)106
Which statement best describes the pH of pure water?
(A)It is neutral because the concentration of hydronium ions equals that of hydroxide
ions.
(B)It is neutral because the pure liquid contains neither hydronium ions nor hydroxide
ions.
(C)It is acidic because it has a hydronium ion concentration of mc027-1.jpg.
(D)It is basic because it has a hydroxide ion concentration of mc027-2.jpg. - ANS-(A)It is
neutral because the concentration of hydronium ions equals that of hydroxide ions.
A solution containing HCl would likely have
(A)a high pH and a low pOH.
