Question

Buffers can resist pH change by providing a weak base to neutralize added acid? true or false

@eric_d @amematsro  I believe it is false

anonymous · Answer

The answer is actually true, buffers work by adding a base or an acid and its conjugate base or acid to limit ph change

In my review sheet it says a buffer converts a strong base into a weak base. and a buffer converts  strong acid into a weak acid

anonymous · Answer

If we mix a weak acid (HA) with its conjugate base (A-), both the acid and base components remain present in the solution. This is because they do not undergo any reactions that significantly alter their concentrations. The acid and conjugate base may react with one another, HA + A- → A- + HA, but when they do so, they simply trade places and the concentrations [HA] and [A-] do not change. In addition, HA and A- only rarely react with water. By definition, a weak acid is one that only rarely dissociates in water (that is, only rarely will the acid lose its proton H+ to water). Likewise, since the conjugate base A- is a weak base, it rarely steals a proton H+ from water. from http://chemcollective.org/activities/tutorials/buffers/buffers3

so it is true?

this "a buffer converts a strong base into a weak base" couldn't be more wrong
