What is buffer solution and how does it work

A buffer solution is one that refuses to modify in pH after adding to the little amount of acid or base. A buffer is the mixture of an acid-base aqueous solution adjusted to an exact pH value.

Their resistance to modifying the pH makes the buffer solution most helpful for chemical manufacturing and is necessary for many processes of biochemical. In the ideal buffer for a specific pH has a pKa equivalent to the pH desired, because in this solution, the buffer has an equal quantity of base and acid and the buffering capacity is in the middle of the range. Buffer solutions are required for pH to remain right for enzymes in several organisms. Various enzymes work just under very specific conditions, If the pH is too far from the margin, the enzyme may slow down or stop working and refuse, thus eternally stop its catalytic activity. Industrially, the buffer solution is used in processes of fermentation and is used to set the right conditions for the colors used in color to fabrics. They are also used in chemical analysis, chromatographic analysis, dissolution and calibration of pH meter and some other instruments.
