How are buffer solutions used?
Buffer solutions are used to keep the pH nearly constant, especially in biochemical and commercial applications.
Buffers are used to run biochemical assays. For example, enzyme activity varies with pH, so you have to keep the pH constant to get accurate results.
Buffer solutions are used in medicines that require a constant pH.
Many household products use buffers. For example, adult shampoos are buffered to prevent skin irritation by components like sodium hydroxide.
Baby lotion is buffered to a slightly acidic pH of six. This relieves rashes by inhibiting the growth of bacteria and other pathogens.
Many paints and oils are buffered to maintain standard industrial requirements.
Beer, wine and liquor manufacturers often add buffers to prevent excess acidity during the fermentation process.
The textile industry uses buffers to keep the pH within narrow limits during dyeing and fabric processing.
Many laundry detergents use buffers to prevent their natural ingredients from breaking down.
