Chromatography might be of different types, such as: (a) Paper, (b) Thin-layer, (c) Column, and The amino acids are separated between a stationary and a mobile [...]
In this article we will discuss about:- 1. Nature of Chemical Reactions 2. Rates of Chemical Reactions 3. Types. Nature of Chemical Reactions: Let us look at a very simple example of a chemical reaction and consider what happens when two hydrogen atoms approach one another. For our purposes, a hydrogen atom is, simply, a positively charged proton and a [...]
After reading this article you will learn about the oxidation and reduction reactions of substances. A chemical reaction can be defined as a change in which a substance (or substances) is changed into one or more new substances. In redox reactions both reduction and the oxidation processes go on side-by-side. The oxidation and reduction reactions can be explained in three [...]
