Because these components can neutralize added H⁺ or OH⁻, buffers are highly resistant to changes in pH.

In the first approach, a certain amount of a weak acid (or weak base) is neutralized with a strong base (or strong acid), forming a conjugate acid–base pair in solution. In the second approach, a weak acid (or weak base) is combined with a salt containing its conjugate base (or conjugate acid).

They consist of a weak acid and its conjugate base, which exchange protons and hydroxide ions to form water. The Henderson-Hasselbalch equation expresses the pH as a function of the PKa and the ratio of the base and acid concentrations. video https://cdn.kastatic.org/googleusercontent/FqGS1Fqtfl3zSwzBrnFPEfwxqTEQ2hujYto6c0Wnj5NtXg00xUfaCnT5dLGM-MYJEPAhQALx3ylwm5XJqPFOX8Jt Buffer solutions Buffer solutions maintain a stable pH by neutralizing added acids or bases.
