How can large changes in pH levels affect reaction?

1.What happens when an acid or a base is added to a buffer solution?



thank you in advanceHow can large changes in pH levels affect reaction?
Buffers are designed to maintain a relatively constant pH when acids or bases are added to a mixture.



However, buffers do have a capacity limit. This means that if too much acid or base is added the buffer will be ineffective and the pH can change drastically.



Some of the factors affecting the capacity of a buffer are:



Vo.ume of the buffer solution. The larger the volume the

more acid or base it can accommodate.



Concentration of the buffering materials. The more

concentrated, the more acid or base it can accommodate.How can large changes in pH levels affect reaction?
if little amounts of these are added nothing happens to pH.thts how we define buffer solution
