Gas Chromatography-Mass Spectrometry (GC-MS) combines two sophisticated methods to identify chemicals. Although GC-MS studies may be used with solid, gaseous, and liquid samples, they are most often limited to volatile and semi-volatile substances. The components of a mixture are separated … Read more
A solute is a substance that dissolves in a solution. In a fluid, the solvent is more abundant than the solute. A chemical solution’s concentration is determined by comparing the amount of solute to the amount of solvent. A typical … Read more
The main component of the nitrogen cycle is the element nitrogen in the air. The air we breathe is composed of 78% nitrogen, 21% oxygen, and other trace gases. Nitrogen (N) is a necessary component of the building blocks of life, … Read more
Gel filtration chromatography, also widely recognized as size exclusion chromatography, is a versatile technique for separating proteins and other biological molecules. Gel filtration chromatography separates proteins solely based on molecular size variations. The alternate names for gel filtration chromatography are size … Read more
One of the most commonly used acid-base indicators for determining the endpoint in acid-base titrations is phenolphthalein. In some laxatives, it serves as the active component. However, due to the substance’s alleged carcinogenicity, phenolphthalein is no longer used as a … Read more
The Avogadro constant is used to calculate moles. A mole is a chemical unit that represents 6.02214076 * 1023 entities. This is known as the Avogadro constant and is denoted by the symbol mol. To count atoms and molecules, chemists … Read more
In chemistry, the term “solution” refers to a homogeneous mixture of two or more substances in relative amounts. Although the term “solution” refers to the liquid state of matter, solutions of gases and solids are also possible. What is the … Read more
If the chemical equilibrium is the result of two active and opposing reactions, the system’s equilibrium is referred to as a dynamic equilibrium. Dynamic equilibria occur when there is no observable change in a reaction, but the system is still … Read more
The shapes of organic molecules are best visualized using molecular models. Organic compounds have three dimensions, and the preferred spatial arrangement of the covalent bonds determines how they are shaped. The existence of double and triple bonds is explained by … Read more
