A buffer system is set up with [tex][H_a]=2[-a][/tex]. if [tex]p_{ka}=5.5[/tex], the pH of the buffer is 5.2.
What is a buffer system?
- A buffer system is a solution that prevents change in pH when acids or bases are added to the solution. They are made of either a weak acid and its salt or a weak base and its salt.
- The ratio of HX/X- does not change enough to affect pH significantly, when an acid or a base is added to a buffer.
What are the 3 buffer systems in the body?
The body's chemical buffer system contains of three different buffers:
- The carbonate/carbonic acid buffer
- The buffering of plasma proteins.
