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 0.360 M in both formic acid (HCOOH) and its conjugate base (HCOO–). 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 175 mL of a buffer that is 0.440 M in both hydrofluoric acid (HF) and its conjugate base (F–). Calculate the maximum volume of 0.460 M HCl that can be added to the buffer before its buffering capacity is lost. THE ANSWER IS NOT 1.34 X 10^-4

2. Buffer capacity refers to the amount of acid or base a buffer can “absorb” without a significant pH change. It is governed by the concentrations of the conjugate acid and base forms of the buffer. A 0.5 M buffer will require five times as much acid or base as a 0.1 M buffer for given pH change. In this problem you begin with a buffer of known pH and concentration and calculate the new pH after a particular quantity...

"Acid-base buffers are most effective when the target pH of the buffer solution is close (within one unit) to the pKa of the conjugate acid in in the conjugate acid/base pair to be used in the buffer. This is called the buffer range for a particular acid/base system. For the three questions below, select the two compounds from the list which could be most effectively combined to create a buffer at the target pH. You will not need to use...

You decide to use formic acid 1.5l of 70mM buffer and you find the concentrationsto be 0.025M of formic acid and 0.045M of its conjugate base, you find that you can buy 19M formic acid from a chemical company. a) what volume of 19M formic acid should you start with? b) Would you make your desired buffer by adding strong acid (0.5 M HCl) or strong base ( 0.5M NaOH) why? c) How many mL of either the strong acid...

A beaker with 175 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.80 mL of a 0.490 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.740. Express your answer numerically to two decimal places. Use a minus (-) sign if the pH has decreased.
