A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. 13.4Add strong acid H+ (aq) + CH3COO (aq) CH3COOH (aq) Add strong base OH (aq) + CH3COOH (aq
The mechanisms of HCOOH/HCOO– oxidation on Pt
The pH effect and the H/D kinetic isotope effect (KIE) for the oxidation of formic acid/formate anions (FOR) on Pt(111) have been studied. The pHdependent FOR activity displays a volcano shape with a maximum at a pH close to the pK a of HCOOH. The H/D KIE factors for HCOOH/DCOOH or HCOO /DCOO are ca. 5, 2, and 1 in solutions with pH = 1.1, 3.6, and 13, respectively.

C) HCOOH and HCOOK A buffer contains significant amounts of a weak acid and a salt containing its conjugate base. The acid consumes any added base, and the base consumes any added acid. In this way, a buffer resists pH change. Strong acids, strong bases, two bases, or two acids cannot form a buffer
equilibrium Calculate pH of a buffer solution
If you compare it with a 1:1 buffer where the pH = pKa, it decreased because there is a higher concentration of acid than conjugate base. If you compare it to the pH of 0.3 M formic acid (roughly pH = 2.1), then it increased because you added conjugate base (neutralized and diluted the acid).
