Introduction The phrase 'destructive distillation' refers to the procedure of processing organic materials using specific reagents, restricted quantities of oxygen, solvents, as well as catalysts such as steam or even phenols. Destructive distillation may alternatively be described as the use of pyrolysis techniques. This would be accomplished at extremely high temperatures as well as in relatively inert environments. Coal is frequently exposed to harmful distillation. It is conducted to provide a diverse variety of commercially significant items. Ammonium hydroxide, coke, carbon, coal tar, coal gas, as well as coal oil are examples of economically relevant products. What is Destructive Distillation? ... Read More

Introduction Pure substances are elements that cannot be broken further like oxygen, metals and metals, non-metals, etc. In contrast, mixtures are combinations of two or more elements mixed like lemonade. We should not be getting confused with pure substances and mixtures. They are two separate entities. Pure substances are pure elements that can’t be broken further into smaller entities. They can be in any state of matter like liquid, solid, or gas. The mixtures are combinations of two or more elements or substances just understood by a simple example. Water is composed of two elements hydrogen and oxygen in a ... Read More

Introduction Chemistry is indeed the scientific study of these three types of matter: elements, compounds, as well as mixtures. A compound is developed if two or more individuals interact chemically as well as mix in a fixed proportion. A chemical expression that represents the ratio wherein the components have interacted to yield a compound. Molecular compounds, as well as salts, are examples of compounds. A mixture is formed when two or more elements have been mixed collectively in such a way that they often not react chemically but also keep all of their characteristics. Substances merely merge physically yet do ... Read More

Introduction John Mayow, the English physician of 1674 discovered that air is not a single element, it is a mixture of different kinds of gases. The discovery made by scientists is wide to get a clear idea about the composition of air. Joseph Priestley, a chemist 1774 discovered the presence of Oxygen in the air. Joseph Black, a chemist of 1750 discovered the presence of Carbon dioxide in the air. Noxious air, now known as Nitrogen gas, was discovered by Daniel Rutherford in 1772. Henry Cavendish in 1785 was not satisfied with the components present in the air since 0.7% ... Read More

Introduction Physical separation methods are such methods in which the chemical and physical attributes of elements of any mixture remain the same after separation. Almost all separating methods are useful and widely applied in the current times for different industrial and home purposes. The physical separation method is a supportive and useful method of segregation. What is physical separation? Physical separation is associated with differentiating some components based on their structure, gravity, magnetic attributes and some other natures. The optical properties and electrical attributes are also important considerations that are required at the time of separating components in a ... Read More
