Calculate the pH of each of the following solutions:
(a) 2.8 x 104 M Ba(OH)2, (b) 5.2 x 10- M HNO3.
- pH of Saliva The pH of saliva is normally in the range of
6.4 to 7.0. However, when a person is ill, the person's saliva
becomes more acidic.
(a) When Marco is sick, he tests the pH of his saliva and
finds that it is 5.5. What is the hydrogen ion concentra-
tion of his saliva?
(b) Will the hydrogen ion concentration in Marco's saliva
increase or decrease as he gets better?
(c) After Marco recovers, he tests the pH of his saliva, and it
is 6.5. Was the saliva more acidic or less acidic when he
was sick?
Lactic acid, HC3H5O3, is a weak acid; write an equation for its ionization in aqueous solution. If 0.15 M solution of lactic acid has pH = 2.34, calculate the molar concentration of H3O+in the solution. What are the Ka of lactic acid and the degree of ionization of the acid?
