Buffers

[carterwink2K]

What would we need a buffer for? Is there like an industry standard that is the best buffer?

[Elaine Steinberg 3H]

One super important buffer system exists in our blood! Since cells/enzymes in the body can stop functioning if the pH gets too high or low, blood must use a buffer system to maintain a pH of about 7.4. Specifically, carbonic acid (acid) and bicarbonate ions (conjugate base) in the bloodstream are responsible for this.

[Anjali Botcha 3B]

Buffer solutions are solutions of an acid and its conjugate based, and they are useful in chemical reactions because of their ability to resist any changes in pH. Some reactions might require a consistent pH, so a buffer will neutralize the solution if an acid or base is added. I'm not sure about the standard buffer though.

Buffers are important so that dramatic changes in pH don't occur if you add a acidic/basic substance into the system, especially when you want a stable pH range.

[Ashley Presnell 1C]

Buffers are helpful not only in labs but in biological systems to minimize changes in pH. There is no universal buffer that works for everything as we choose a buffer dependent on the pH of the desired solution, and choose a pKa close to that pH value to minimize changes in pH. For example, shampoo is a common everyday example of a buffer in which some use citric acid as a buffer to prevent the alkalinity of certain chemicals in shampoo from having harmful effects on the scalp.

Buffer are super important for the body to maintain equilibrium!

[Molly Smith 1J]

Buffers are to keep a substance from becoming either too basic or too acidic. In other words, when one needs a stable ph for a solution under chnaging conditions, a buffer should be used. The buffer will accept H+ given off by acids and will also provide H+ for bases to take up. Example: if NaOH is added to the solution with the buffer, the buffer will provide H+ to turn OH- into H2O.

[Matthew Vu 3C]

Buffers are important because they can resist pH changes, which are important in a lot of biological systems. For example, enzymes will be denatured if the pH of its environment changes too much, so buffers can prevent this pH change.

One industrial application is eye drops. Here buffer is used to stabilize the pH in the eye layers.

Buffers are important to maintain equilibrium and resist major pH changes in our body!

[Ashrita Singh 2F]

Buffers help maintain equilibrium by reducing the effect of significant changes in pH.

Buffers are important so that dramatic changes in pH don't occur when you add an acidic or basic substance into the system.

[andreagutierrez 3K]

Buffers are important in order to maintain an equilibrium.

[JasmineReyes-2K]

Hi!,
Buffers are important because an equilibrium needs to be maintained

[Guadalupe_3B]

A buffer is important because it is able to neutralize small amounts of added acid or base to maintain the pH of the solution stable.

[oliviahelou]

In order to maintain equilibirum!

[205678283]

It is an important distinction to note that an optimum buffer solution has an equal amount of acid and conjugate base, under which circumstances the pH=pKa

[N Kanuri 2E]

Buffers are super important because, especially within biological systems, they minimize pH changes and help to maintain equilibrium for systems! They are resistant to changes in acidity and basicity!

[Jessica Li 1G]

A buffer is applied to resist pH changes when adding acidic/basic substances. It does this by neutralizing these added components to stabilize pH.

[Kainath Kamil Dis 2K]

They keep the pH of a system stable.

[14b_student 2E]

Buffer help us maintain equilibrium and balance the pH in a solution.

[Aeson Salcedo 3L]

Buffers are used to maintain pH. Because of this they are used a lot in our body.

[Ava Ward 1K]

Buffers are usually needed to maintain a certain pH during a reaction or process. One example is during gel electrophoresis, which is used to separate DNA segments by size. A common buffer in this case is TAE, which stands for tris-acetate-EDTA. The main goal of TAE is to influence the electronic current, as other liquids are not able to conduct electricity.
