Here is the answer for the question – A buffer consists of undissociated acid (HA) and the ion made by dissociating the acid (A-). How does this system buffer a solution against decreases in pH?. You’ll find the correct answer below

A buffer consists of undissociated acid (HA) and the ion made by dissociating the acid (A-). How does this system buffer a solution against decreases in pH?
(a) HA dissociates and releases H+ and A- into solution.
(b) A- reacts with H+ to become HA.
(c) As the solution loses H+, HA replaces the lost H+.
Both (a) and (c).
None of the above.
The Correct Answer is
(b) A- reacts with H+ to become HA.
Reason Explained
(b) A- reacts with H+ to become HA. is correct for A buffer consists of undissociated acid (HA) and the ion made by dissociating the acid (A-). How does this system buffer a solution against decreases in pH?
