Question Answer
What is bronsted-lowry acid? a proton donor
what is a bronsted-lowry base? a proton acceptor
explain what happens to a buffer when an acid is added to it 1. H+ ions react with the A- to produce more HA. 2. The [A-] and [HA] are very large so an increase in [HA] doesn't affect the pH of the solution
explain what happens to a buffer when a base is added to it. 1. OH- reacts with H+ ions to produce water. 2. The position of equilibrium is then shifted to the right to produce more H+ ions.
what is the function of the weak acid component in a buffer solution? to act as a source of HA which can remove any added OH-
what is the function of the salt component of a buffer? to provide A- ions that can react with H+ ions to produce HA.
