17.2b Buffer pH #1 Calculate pH of a weak acid/conjugate base buffer solution: Calculate the pH of 620. mL of a 0.151-M solution of hydrocyanic acid before and after the addition of 0.277 mol of potassium cyanide. pH befor addition = pH after addition =
Which concentration of a weak acid (HA) and its conjugate base (A-) will make a buffer solution whose pH value is equal to its pKa? (HA) = 0.05 M, (A-) = 0.07 M HA = 0.05 M, (A-) = 0.05 M more than one answer is correct HA = 0.05 M, (A-) = 0.01 M
If a buffer solution is 0.570 M in a weak acid (?a=4.3×10^−6) and 0.260 M in its conjugate base, what is the pH?
a buffer is a solution that has a Weak acid in equlibirum with its conjugate base. So can a buffer solution has a weak base in equlibirum with its conjugate acid? So basically, to create a buffer, you can mix a weak acid with its conj. base OR a weak acid + strong base OR a weak base with a strong acid? Am i Correct?
A buffer solution is made by adding 1.00M weak acid (pKa=4.45) to 1.25M solution of its conjugate base to make 100 mL of buffer solution. Calculate the pH after 75.0 mL of 0.725 M strong acid has been added.

A buffer is a solution that is a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. When strong acids or strong bases are added, buffers either accept protons when they are in excess or donate protons when they have been depleted to minimize changes in pH. Which of the statements correctly describe the properties of a buffer? Select one or more: a. The weak base of an alkaline buffer will...
