What is buffer solution example?

An acidic buffer solution is simply one which has a pH less than 7. Acidic buffer solutions are commonly made from a weak acid and one of its salts - often a sodium salt. A common example would be a mixture of ethanoic acid and sodium ethanoate in solution.

What is the use of buffer amplifier?

A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level. The interposed buffer amplifier prevents the second circuit from loading the first circuit unacceptably and interfering with its desired operation.

What is the purpose of a buffer solution in biology?

Biological Buffers: Reviewing the Basics. Basically, buffers are molecules that donate or accept protons to resist changes in pH as acids or bases are added to the solution. A buffer consists of a weak acid and its conjugate base, or a weak base and its conjugate acid.
