Calculate the expected buffer capacity of the acetate buffer based on the number of moles of CH3CO2H in the buffer. (hint, you know the concentration and volume) In other words, how many moles of NaOH are needed to break the buffer? Does the measured buffer capacity of acetate buffer (20mL) meet your expectations? pKa = 4.74 target pH= 4.9 [HA]= 2.04x10-2 M [A] = 2.96x10^-2 M

Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 175 mL of a buffer that is 0.140 M in both formic acid (HCOOH) and its conjugate base (HCOO-). Calculate the maximum volume of 0.460 M HCl that can be added to the buffer before its buffering capacity is lost.

Buffer capacity is a measure of a buffer solution's resistance to changes in pH as strong acid or base is added. Suppose that you have 145 mL of a buffer that is 0.100 M in both propanoic acid (C2H5COOH) and its conjugate base (C2H5COO−). Calculate the maximum volume of 0.420 M HCl that can be added to the buffer before its buffering capacity is lost.

Prediction? 1. How will the addition of an inert salt affect the PH and buffer capacity of a buffer? 2. What will happen to the ph and buffer capacity of a buffer when it is heated? what factors contribute to the answer? 3. What will happen to the ph of the solution when a buffer breaks down upon addition of acid? 4. What will happen to the ph of the solution when a buffer breaks down upon addition of base?

Buffer capacity is a measure of a buffer solution\'s resistance to changes in pH as strong acid or base is added. Suppose that you have 135 mL of a buffer that is 0.400 M in both acetic acid (CH3COOH) and its conjugate base (CH3COO–). Calculate the maximum volume of 0.340 M HCl that can be added to the buffer before its buffering capacity is lost.

Buffer capacity is a measure of a buffer solution\'s resistance to changes in pH as strong acid or base is added. Suppose that you have 125 mL of a buffer that is 0.400 M in both propanoic acid (C2H5COOH) and its conjugate base (C2H5COO–). Calculate the maximum volume of 0.290 M HCl that can be added to the buffer before its buffering capacity is lost.

Buffer capacity is a measure of a buffer solution\'s resistance to changes in pH as strong acid or base is added. Suppose that you have 115 mL of a buffer that is 0.180 M in both acetic acid (CH3COOH) and its conjugate base (CH3COO–). Calculate the maximum volume of 0.100 M HCl that can be added to the buffer before its buffering capacity is lost.
