Buffers?
Are buffers just a weak acid and its conjugate base? As a buffer must have a source of protons to neutralize a base or acid

Re: Buffers?
Hello!
A buffer is a solution that has the ability to resist changes to pH that are caused by adding an acid or a base. A buffer is made by either having an acid and its conjugate base in a solution at equal amounts or by having a base and its conjugate acid in a solution at equal amounts as this would enable acids and bases to be neutralized by the solution. I hope this helps!

Re: Buffers?
Yes, a buffer is a solution containing a weak acid and its conjugate base. However, a buffer solution usually contains a salt that has the conjugate base, because a weak acid typically won't have even amounts of acid and conjugate base, since it does not fully dissociate. This extra conjugate base from the salt makes it so that there is an even amount of weak acid and conjugate base.

Re: Buffers?
a buffer solution consists of a weak acid and its conjugate weak base. it also resists change in pH, since the weak base reacts with the H+ causing the pH to go up and the weak acid reacts with the OH-, bringing the pH back down.

Re: Buffers?
Buffers can consist of a weak acid and conjugate base or can contain a weak base and its conjugate acid, as it needs these acids and bases in order to remove any added H+ ions or accept them. These buffer solutions, thereby, can effectively neutralize the addition of strong bases or acids and help resist large pH changes.

Re: Buffers?
Buffers are used to neutralize the system in case there are any additions to the solution that might affect the pH. They come in the form of a weak acid's conjugate base or a weak base and its conjugate acid.

Re: Buffers?
Yes, a buffer is when a solution does not change pH regardless of acid/basic components being added. This means that the solution is able to neutralize small amounts of these components to make the pH relatively stable. To maintain pH, a buffer needs to either have a weak acid as its conjugate base or a weak base as the conjugate acid.

Re: Buffers?
An acidic buffer can be made from a an aqueous solution of a weak acid and a solution of the salt of its strong conjugate alkali. For example, CH3COOH and NaCH3COO can be mixed to make an acidic buffer. A basic buffer, on the other hand, can be made from an aqueous solution of a weak base and a solution of the salt of its strong conjugate acid. For example, NH3 and NH4Cl can make a basic buffer.

Re: Buffers?
Buffers have a weak acid and a conjugate base and allows for the acids and bases to be neutralized in the solution.
