- 8-58 What is the connection between buffer action and Le Chatelier's principle?arrow_forward8-55 We commonly refer to a buffer as consisting of approximately equal molar amounts of a weak acid and its conjugate base—for example, CH3COOH and CH3COO-. Is it also possible to have a buffer consisting of approximately equal molar amounts of a weak base and its conjugate acid? Explain.arrow_forward8-50 The usual concentration of HCO3- ions in blood plasma is approximately 24 millimoles per liter (mmol/L). How would you make up 1.00 L of a solution containing this concentration of HCO3- ions?arrow_forward
- 8-53 Write equations to show what happens when, to a buffer solution containing equimolar amounts of CH3COOH and CH3COO-, we add: (a) H3O (b) OH-arrow_forward8-60 How is the buffer capacity affected by the ratio of the conjugate base to the conjugate acid?arrow_forward8-62 What is the pH of a buffer solution made by dissolving 0.10 mol of formic acid, HCOOH, and 0.10 mol of sodium formate, HCOONa, in 1 L of water?arrow_forward
- 8-96 Suppose you want to make a CH3COOH/CH3COO- buffer solution with a pH of 5.60. The acetic acid concentration is to be 0.10 M. What should the acetate ion concentration be?arrow_forward8-44 What is the molarity of a solution made by dissolving 3.4 g of Ba(OH)2 in enough water to make 450 mL of solution? Assume that Ba(OH)2 ionizes completely in water to Ba2+ and OH- ions. What is the pH of the solution?arrow_forward8-82 Assume that you have a dilute solution of HCI (0.10 M) and a concentrated solution of acetic acid (5.0 M). Which solution is more acidic? Explain.arrow_forward
- 8-51 What is the end point of a titration?arrow_forward8-63 The pH of a solution made by dissolving 1.0 mol of propanoic acid and 1.0 mol of sodium propanoate in 1.0 L of water is 4.85. (a) What would the pH be if we used 0.10 mol of each (in 1 L of water) instead of 1.0 mol? (b) With respect to buffer capacity, how would the two solutions differ?arrow_forward8-112 Consider an initial 0.040 M hypobromous acid (HOBr) solution at a certain temperature. At equilibrium after partial dissociation, its pH is found to be 5.05. What is the acid ionization constant, Ka, for hypobromous acid at this temperature?arrow_forward
