Question

List out any three uses of buffers.

Answer 1

Buffers are also important in certain commercial household products. Shampoo, for example, contains buffers of citric acid and sodium hydroxide, which work to balance out the natural alkalinity of soap, which would otherwise burn the scalp.

Buffers don't just aid in aspects of everyday life that are good for the health, however. Central to alcohol production is a process called "fermentation," wherein sugars convert to alcohol in the absence of oxygen.

Perhaps their most pertinent everyday application, buffers are never in short supply within the human body. A buffer of carbonic acid (H2CO3) and hydrogen carbonate (HCO3-), for example, work in unison to keep the pH of the bloodstream at a neutral 7.4.
