A buffer solution that is 0.100 M in both HCOOH and HCOOK has a pH = 3.75. A student says that if a very small amount of 0.100 M HCl is added to the buffer, the pH will decrease by a very small amount. Which of the following best supports the student's claim? (A) HCOO will accept a proton from HCl to produce more HCOOH and H2O(B) HCOOH will accept a proton from HCl to produce more HCOO and H2O. (C) HCOO wil donate a proton to HCl to produce more HCOOH and H2O (D) HCOOH will donate a proton to HCl to produce more HCOO and H2O.

![pk_{a} + log \frac{[HCOO^{-}]}{[HCOOH]}](/tpl/images/0531/9252/8a009.png)
is directly proportional to pH. Hence, when there occurs a decrease in the pH of the solution the ![[HCOO^{-}]](/tpl/images/0531/9252/bee9e.png)
will also decrease. 
, best supports the student's claim.
