Introduction High-density polyethylene would be a thermoplastic polymer. The monomer unit is ethylene. High-density polyethylene is also known as PEHD (Polyethylene High Density), polythene alkathene, and polythene. When a plastic substance has the Resin Identification Code (RIC-2) symbol, it is manufactured of HDPE. It is commonly abbreviated as RIC-2. Later, HDPE might have been recognized as an essential raw material within the manufacture of a wide range of products. It contributes to even more than 34 percent of the worldwide plastic industry. You've undoubtedly seen doctors wearing special disposable attire when treating a corona patient. You'll be amazed to hear ... Read More
Introduction Catalysis is the process of altering the reaction rate by utilising a chemical that is not used by the reaction. As a result, it does not show any change in the total stoichiometry of the process, but it must occur in at least a single elementary process in the catalysed reaction mechanism. Although the catalysed route has smaller activation energy, the total energy shift that comes from the reaction is unaffected by the existence of a catalyst. Nonetheless, because of its smaller activation energy, a catalysed reaction has a quicker rate of reaction than an uncatalyzed reaction at a ... Read More
Introduction In crystalline solids, any irregularities or distortion observed around a particular point, or an atom is called a point defect. Defects occur when crystallisation takes place at a very fast or intermediate rate. As a result of which the particles or atoms do not get enough time to arrange themselves in a regular pattern. Point defects are further classified into three categories, and they are − Stoichiometric defects (st.), Impurity defects and Non-Stoichiometric defects. In Stoichiometric defects, the ratio of cations (positive charge) and anions (negative charge) remains unchanged. An impurity defect occurs when an external (foreign) atom occupies ... Read More
Introduction Iron is uncommon in the Earth's crust in its metallic state and is mostly deposited by meteorites. Clean iron plates are flawless and mirror-like silver-grey. However, iron often forms brown to black moist iron oxides, sometimes termed rust, when combined with oxygen and water. Chemically, iron's two most frequent oxidation states are iron(II) and iron(III). Iron has several characteristics in common with additional transition metals. It makes up a large portion of both the exterior and interior cores of the planet and is, by weight, the second highest prevalent element after oxygen. What is Iron? The simplest widespread ...

Introduction Johann Rudolf Glauber, a German scientist, made the initial discovery of KMnO4 synthesis in 1659. This chemical is soluble in water and is dreamed up of potassium and permanganate ions. In its physical condition, it is a dark purple and odourless solid. It is often referred to as Permanganate of Potash or Condy's crystals. As a potent oxidizing agent, dermatitis medicine wound cleaner, and general disinfectant, potassium permanganate is frequently employed in the chemical process industries and laboratories. What is Potassium Permanganate? An inorganic substance with the scientific formula KMnO4 is potassium permanganate. It is a crystalline salt ... Read More
Introduction The systematic analysis of cations presents inside the element comes to aid many professionals from the field of chemistry to understand the properties of these elements. The experiment shows the quality of cations and their quantity that is observed to lie inside a chemical compound. Aim of the experiment The aim of the experiment is to understand the total amount of cations that lies in a mixture of salt. These inorganic salts consist of required amount of cations that have various properties. Theory of the experiment The theory of this experiment is to take an approach in order to ... Read More
Introduction Tannic acid is one type of tannin and these two terms are used “interchangeably”. A “tannic acid” is a form of "tannin" and "one type of polyphenol". It can be used in “the food industry and medical field”. It can cause damage to the "eye, skin and even to the respiratory system". Tannins are the basic ingredients for the “chemical staining of woods”. What is Tannic Acid? “Tannic acid” can be defined as a “type of polyphenol” and it is an “organic molecule”. The chemical formula that can represent tannic acid is “$\mathrm{C_{76}H_{52}O_{46}}$”. It can be referred to as ... Read More
Tantalum was discovered by Anders G. Ekeberg (1802), and he discovered this metal in Uppsala, Sweden, in the minerals tantalite from Finland and yttrotantalite from Sweden. Later English chemist William Wollaston declined his discovery. Not only that, but he also claimed that it was another kind of material known as the niobium, in the year 1903; the tantalum was refined by other chemist named, Werner Von Bolton. What is Tantalum? The term Tantalum is derived from a Greek mythological character, named Tantalos, who was one of the villains. In 1903, Werner Von Bolton gave this name because it was ... Read More
Introduction Tartaric acid is a common organic acid that is mostly in citrus fruits. This acid found to be white in colour and it occurs in crystalline form. This acid is combined with sodium bicarbonate and is utilised as baking powder. It is useful as a leavening agent for the preparation of food. What is tartaric acid? Tartaric acid is an organic compound that is di-carboxylic in structure. The molecular formula of this compound is C4H4O6. It is also acknowledged as racemic acid. This compound has two distinct stereo centres. The IUPAC name of this chemical compound is 2, 3-dihydroxybutanedioic ... Read More
Introduction Polytetrafluoroethylene commonly known as Teflon refers to a synthetic type of element made of “tetrafluoroethylene fluoropolymer”. It is mainly created by the “radical polymerisation” that is free of several molecules of tetrafluoroethylene. Polytetrafluoroethylene is called PTFE as the chemical term that has numerous benefits in the current situation to all types of industries. What is Teflon? Teflon refers to a name that has been widely used in the making of non-stick material, especially for the cookware set. This is mainly made with a particular chemical bond namely tetrafluoroethylene. It refers to a thermoplastic element of polymer and the chemical ... Read More
