The Usefulness of Buffers Buffer solutions are one of the most important types of chemical reagent used in chemical research, biological research and industry. Their usefulness stems mostly from their ability to resist changes in pH. If you paid attention in science class, you may recall that pH...
Good's buffers are excellent and widely used in a variety of biological experiments, but there are still problems. For example, The piperazine-based species (PIPES and HEPES) have a rather rich redox chemistry. In particular, Tris buffer is widely used, but it is not a Good's buffer[4]...

They perform various functions and are used extensively in the fields of histology, cell biology, and patholog...
Amino acids are frequently used as buffers. Describe the pH range of acceptable buffering behaviour for the amino acids alanine, histidine, aspartic acid, and lysine. What functional group of aspirin causes it to irritate the stomach? Why buffers added to some aspirin products? What quantity of ...
What are the purposes of metabolism? Explain. Why is homeostasis important, and what purpose does it serve? Explain how the bicarbonate buffer system adjusts blood ph. How do buffer systems maintain the acid-base balance? Identify and describe the operation of the three major chemical buffers of...
Buffers are mixtures that resist changes in pH when acids or alkalis are added. They play a crucial role in regulating chemical conditions in animals and plants and also in global environmental systems such as the oceans. In this article I use computer-interfaced titrations to demonstrate the ...
As a commonly used buffer, Tris-HCl buffer solutions are widely used in biochemistry and molecular biology to maintain stable pH values for biomolecules such as nucleic acids and proteins[1]. Tris-HCl and Tris Tris-HCl is an acidic buffer, mainly used to prepare buffers with a physiological ...
One way of looking at this process is that the ammonia atom is donating its lone pair to the proton. Because the lone pairs are driving this chemical reaction, we have a new definition of acidity and basicity, called "Lewis acidity/basicity." ALewis baseis a compound that donates an elect...
