Introduction Bismuth Subsalicylate is a commercial drug that is sold over the counter means it can be sold without any prescription. It has the chemical formula ${C_7H_5BiO_4}$. It was developed over 100 years back, in 1901, for the treatment and sanitation of cholera infection. First, in 1939 it was approved by FDA for the treatment of nausea, diarrhoea, and gastrointestinal infections. It is an insoluble salt of salicylic acid. It exhibits the property of antibacterial and antidiarrheal agents. It is used for the treatment of travellers' diarrhoea, nausea, stomach infection, antacid, heartburn, indigestion, etc. What is Bismuth Subsalicylate It is ... Read More

Introduction The scientific reason behind both the physical and the chemical change is important to understand the characteristics of both of these changes. The reversible and irreversible nature of any components is associated with both of these changes. In a physical change, an object’s basic components change in shape, size, and colour. The chemical changes are very much different as it leads to an irreversible change that cannot be avoided while any chemical experiments are undertaken. What is a chemical change? During a chemical change, the atoms and molecules are broken into pieces and form a new component. An individual ... Read More

Introduction Chemical change is the process by which new forms of matter are formed. Combining baking soda and vinegar, is the experiment through which the changes and features of chemical reactions are noticeable. This experiment also distinguishes physical change and chemical change clearly in a matter. The matter's properties are being understood by observing the chemical changes in them. Chemical changes can be observed in varied activities that are performed during daily life from the digestion of food to the explosion of fireworks, and the removal of grime by soap. A chemical change is a form of chemical reaction that ... Read More

Introduction The Birch reduction is a reaction where arenes are transformed into cyclohexadiene. Prof. Arthur J. Birch, an Australian chemist who determined the product's structure in the reduction reaction as a 1, 4-cyclohexadiene derivative in 1944, gave the reaction the name "Birch reduction." For the reduction of benzene (inactivated arenes), birch reductions generally use alkali metals (e.g., Li, Na, or K), which dissolve in Liq. ammonia to provide a solvated electron. Hence, the resulting solution is an astounding hue of blue, even though given metals are only faintly soluble in Liq. ammonia. The object has a deep blue colour because ... Read More

Introduction The Balz-Schiemann (BS) reaction was one of the first procedures for producing fluorinated aromatic compounds but is still commonly used today. The thermal breakdown of diazonium tetrafluoroborate by diazotization of the corresponding aromatic amines introduces a fluorine atom into aromatic rings in this process. This reaction is notably essential for the synthesis of fluorinated aromatic compounds, whose breakdown in the lack of solvent generally yields a reasonably excellent yield of aromatic fluorides. The BS reaction has been thoroughly studied or shown to be beneficial in the synthesis of aromatic halides. What is Balz Schiemann Reaction ? The BS reaction ... Read More

Introduction At present, there are 118 elements that are known to us and from them, 92 elements occur naturally. The other metals within the total list are prepared with the help of artificial methods. However, elements are classified into several categories, that includes, metals, metalloids and non-metals based on their respective properties and are correlated with respect to their periodic table. There are several physical and chemical properties, that are noticed among metals. What are metals? Both metals and non-metals are found within our surroundings and are quite essential in their presence. Metals can be defined as the substances that ... Read More

Introduction Barium Carbonate has a molecular formula, (BaCO3). It is an inorganic chemical compound. It is tasteless and odourless. Like or similar to most of the other alkaline earth metal carbonates, it appears as white salt and it is insoluble or poorly soluble in water solution but, it is soluble in most of the acids, except sulphuric acid. It is one of the very important barium compounds commercially or economically. Although it is not soluble in pure water it is partially or slightly soluble in water saturated with carbon dioxide (CO2). It is used for the formation of rat poisons. ... Read More

Fractional distillation is useful for separating a mixture of substances with minor differences in boiling points. The minor difference means the gap between the boiling points should be less than 25 Kelvin.It is used for the distillation of crude oil in the petroleum industry thereby resulting in the manufacturing of gasoline, lubricating oil, diesel, and plastics.What is Petroleum Refining?Petroleum refining is defined as the process of converting crude oil into useful products. The process involves separation, conversion, and treatment. Crude oil is heated in a furnace so that hydrocarbons can be separated by fractional distillation since there is not much ... Read More
