How does a buffer resist change in pH upon addition of a strong acid?

How does a buffer resist change in pH upon addition of a strong acid?

  • The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H^+ ions in solution and therefore only a little change in pH.
  • The strong acid reacts with the weak acid in the buffer to form a weak base, which produces few H+ ions in solution and therefore only a little change in pH.
  • The strong add reacts with the strong base in the buffer to form a salt which, produces few H+ ions in solution and therefore only a little change in pH.

Solutions

Expert Solution

strong acid be H+

It will react with the conjugate base to form a weak acid.

Now we know the weak acid is weakly dissociated, it will not cause change like strong acid

This is how base workd.

The strong acid reacts with the weak base in the buffer to form a weak acid, which produces few H+ ions in solution and therefore only a little change in pH.

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.
