What is a buffer solution?

Answer 1

A buffer solution is a mixture of a weak base and its conjugate acid in appreciable quantities. It acts to resist gross changes in #pH#.

The buffer equation is as follows:

#pH=pK_a + log_10{[[A^-]]/[[HA]]}#

When #[HA]=[A^-]#, #pH=pK_a#. Why?

You'll have to search through these boards for a lot of answers that address these kinds of issues.

A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added to it. It typically contains a weak acid and its conjugate base, or a weak base and its conjugate acid.

A buffer solution is a solution that resists changes in pH when small amounts of acid or base are added to it. It is typically composed of a weak acid and its conjugate base, or a weak base and its conjugate acid, in approximately equal concentrations. Buffer solutions are important in various chemical and biological processes, as they help maintain a stable pH environment, which is crucial for many reactions to occur optimally.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
