A variety of dangerous chemicals are used in industrial manufacturing, either as reagents, solvents, ingredients or cleaning agents. Five examples of hazardous chemicals include:Chromium Zinc Ammonia Benzene MercuryMany of the chemicals used in industrial manufacturing are considered toxic and have the potential to harm or even kill humans and other organisms. The toxic effects can sometimes be acute and...
From acetone to hydrochloric acid, various types of organic and inorganic chemicals are used in the pharmaceutical industry. Some act as solvents or reagents, while others are used as catalysts or active ingredients.Chemicals are vital in the production of a wide range of pharmaceutical products, including medicines, topical ointments, vaccines, food supplements, and special infant milk formulations. While some of these...
Powder explosives, or gunpowder (also known as black powder), is one of the earliest chemical explosives on record. Once widely used as a blasting agent and a propelling charge in guns, it’s now largely been replaced by more modern alternatives.Although it’s believed gunpowder was invented by Chinese monks around the ninth century, it wasn’t until 1846 that the first explosives...
The movie industry traditionally used a variety of chemicals to shoot and process films, including photo developing agents, such as phenidone and hydroquinone-monosulfonate. While the practice has largely been discarded with the advent of digital cinema, chemicals are still used as plot devices in many movies.Celluloid films were predominantly used in cinematography until 1952, when production was discontinued because of...
Distillation is a purification technique that uses heat to extract or separate components from a mixture. The main product of the distillation process is known as the condensate, which is typically a purer substance.The distillation of products from a reaction dates as far back as 4,000 years ago, when ancient civilisations were believed to have used the technique to extract...
EMF, which stands for electromotive force, is the largest possible potential difference between two electrodes of an electrochemical cell when there isn’t a current flowing. It’s measured using the net voltage between the oxidation and reduction half-reactions.Measuring the EMF of an electrochemical cell can help you to determine whether it’s galvanic, meaning whether or not it has an electric current....
Various types of chemicals are used in industrial-scale processing and manufacturing, either as ingredients, reactants, solvents, reagents, buffers, or catalysts. Five of the most common industrial chemicals include sulphuric acid, sodium hydroxide, nitrogen, propylene and ethylene.Industrial chemicals are used to manufacture many in-demand industrial goods, such as distilled petroleum products, plastics, inks, paints, adhesives, cosmetics, and soaps. These products can...
Broadly speaking, there are five types of chemical reactions: Combination Decomposition Combustion Single replacement Double replacement Understanding these different categories can help predict the likely outcome of particular chemical reactions.Chemical reactions take place all around us. The most frequent types of chemical reactions are those that take place inside the cells of living organisms. In the human body, for instance, there...
