so buffers increase when working with hydrogen ions

Solution

Ans. Buffer is a solution that resists change in pH.

For example, a buffer with pH 7.0 does not show change in pH even when small amount of acid or base is added to it. A buffer often contains a weak acid and its conjugate base. When a small amount of acid (say, H⁺ in from of HCL)

Note that resistance in pH change by the buffer is upto a certain threshold value, called buffer capacity. That is, if you add more acid to a buffer, after certain point, change in pH is recorded.

Enzymes are highly sensitive to pH with reduction in catalysis rate on either side of the optimum pH. So, the enzymatic reactions are carried out in buffer solution so that even introduction of a small amount of H⁺ does not change pH. SO, this pH tolerance of buffers is responsible for maintaining optimum pH of reaction mixture and also maintains optimum enzyme activity.

So,

            Buffer increase pH tolerance/ pH resistance when working with hydrogen ions.
