What is a buffer and what is it used for? Buffer Buffer solutions resist extreme pH change when small amount of hydrogen ions or hydroxide ions are present. It is composed of a weak acid and a salt of its conjugate base. Buffer systems are found in biological systems due to its ability...
Traditionally bases have a bitter taste while acids are sour, but in chemistry, the definitions have evolved so that substances are either bases or acids using their chemical properties. This classification is important because acids and bases can react to form salts, and they are the basis of ...

The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
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]. As scientific research advances, it is possible to continue to develop the buffers with excellent performance. For ...
Copper chemistry is very complicated, especially, when both copper (I) and copper (II) chemistry are involved. At the link below, I give a description of a set of experiments I recently did with copper. These really puzzled me, but now I have quite some idea what is happening. ...
