24. A solution of volume 0.500 L contains 1.68 g NH3 and
4.05 g (NH4)2SO4.
(a) What is the pH of this solution?
(b) If 0.88 g NaOH is added to the solution, what will
be the pH?
(c) How many milliliters of 12 M HCl must be added to
0.500 L of the original solution to change its pH to 9.00?
(a) A 50.0 mL solution is prepared to be 1.29 M acetylsalicylic acid. In the first step, 8.55 mL of NaOH is titrated into the solution until the pH is exactly 5.0. What is the concentration of the titrant (NaOH)?
(b) In the second step, enough 5.85 M nitric acid is added to the solution after the titration in part (a) is complete until the pH is one unit lower than the pKa of acetylsalicylic acid. What volume (mL) of nitric acid was added?
The average blood pH is 7.40. The blood volume in humans, on average, is 5 liters. On average bicarbonate concentration in blood is 25 mM. A vinegar jar has a label that says its acetic acid concentration is 3.0%, meaning 3.0 g of acetic acid in 100 mL vinegar. (1) How many mL of vinegar does a person have to intake in order to lower the blood pH to 7.25? (2) if ALL the bicarbonate in 5.0 L of blood is neutralized by vinegar, how many mL of vinegar will be needed? (3) When all the bicarbonate ions are neutralized to carbonic acid, what will be the resulting blood pH?
Note: pKa values for carbonic acid (diprotic acid) are 6.4 and 10.3, respectively.
