Buffer solutions are used to keep pH levels constant in a number of chemical reactions. This is essential for most forms of life that survive only in a relatively small pH range. Blood is an example of buffer solution. More »

In chemistry, a buffer is a substance that is able to resist changes in pH when it is a part of a solution. Buffers are added to solutions to resist acidic or basic compounds. More »

According to a 1963 study at Harvard University, carbon dioxide, bicarbonate and carbonate act as buffers to fluctuating hydrogen ion concentrations in natural sources of unprocessed water, helping the water maintain a r... More »

Buffer solutions are crucial in reactions that require specific pH ranges for them to optimally work because they can resist the changes in pH. They help in neutralization reactions. More »

Buffer solutions play a large role in biochemical functions. Because buffers resist changes in pH levels, they are used to regulate biological functions that only occur at certain pH levels. Buffers can also be used to s... More »

Some examples of miscible solutions include water and organic compounds such as alcohols, aldehydes and ketones. Immiscible solutions include water and many types of oils. A miscible solution is any solution that can be ... More »

The key difference between solutions and mechanical mixtures is that solutions contain dissolved substances whereas mechanical mixtures do not. The components of a solution do not separate when left standing and cannot b... More »
