Electrophoresis vs Electroosmosis Physical separation methods like filtering, distillation, column chromatography are not easy methods when comes to separation of some molecules. Electrophoresis and electro-osmosis are two other separation techniques which can be used to separate charged particles. What is Electrophoresis? Electrophoresis is a technique of separating molecules based on their sizes. Fundamental for […]
Isotope vs Ion Atoms are the small building blocks of all existing substances. There are variations between different atoms. Also, there are variations within the same elements. Isotopes are examples for differences within a single element. Moreover, atoms are hardly stable under natural conditions. They form various combinations between them or with other elements […]
Hot Rolled vs Cold Rolled Steel Rolling is a process where metal is passed through a pair of rollers, to change its shape and make it suitable for certain purposes. Metal rolling has a long history, which takes back to 17th century. Earlier than this, there were slitting mills where flat bars of metal […]
Activated Carbon vs Charcoal Carbon is everywhere. There are millions of compounds, which are made with carbon. We can say that, carbon is the framework for our bodies, plants and micro-organisms. Further, they are in nature, in several forms, as graphite, diamond, charcoal etc. Charcoal Charcoal consists of the element carbon. Carbonic compounds are […]
Geometric Isomers vs Structural Isomers Isomers are different compounds with the same molecular formula. There are various types of isomers. Isomers can be mainly divided into two groups as constitutional isomers and stereoisomers. Constitutional isomers are isomers where the connectivity of atoms differs in molecules. In stereoisomers atoms are connected in the same sequence, […]
Oxidation vs Combustion Oxidation reduction reactions are a basic type of chemical reactions that we commonly come across in life. Oxidation Originally oxidation reactions were identified as the reactions in which oxygen gas participates. There, oxygen combines with another molecule to produce an oxide. In this reaction, oxygen undergoes reduction and the other substance […]
The key difference between sodium chloride and potassium chloride is that the electronegativity difference between K and Cl is higher than that of Na and Cl. Sodium chloride and potassium chloride are ionic compounds. Both are solids, and their cations and anions are in a closely packed structure. These are group 1 metals, which have […]
Amino Acid vs Protein Amino acids and proteins are organic molecules, which are abundant in living systems. Amino Acid Amino acid is a simple molecule formed with C, H, O, N and may be S. It has the following general structure. There are about 20 common amino acids. All the amino acids have a […]
The key difference between aromatic and aliphatic is that aliphatic compounds have straight, branched or cyclic structures whereas aromatic compounds contain a cyclic structure. Organic molecules are molecules that consist of carbons. They are the most abundant molecules in living things on this planet. Organic chemists divide all the organic compounds into two groups as […]
自由能与标准自由能What is Free energy? The amount of work that a thermodynamic system can perform is known as free energy. Free energy can be described using two terms, Helmholtz free energy and Gibbs free energy. In chemistry, when we use the word “free energy” that means Gibbs free energy. […]
