Concentrated sulfuric acid is a versatile chemical used for making fertilizers, dyes, and cleaning metals. The contact method is used to produce it. Safety precautions must be taken when working with it, and it can be diluted with water.
Concentrated sulfuric acid is a chemical used for multiple purposes by producers and processors. It is used to make fertilizers and a variety of other products. It is also used as a drying agent by manufacturers. Sulfuric acid can also be heated and used to dissolve other metals, including lead and copper.
Sulfuric acid was developed in the 16th century. Johann van Helmont is credited with distilling green vitriol and burning sulfur. Concentrated sulfuric acid was first used industrially in the latter part of the 16th century. Over the years, different methods for producing this chemical have been developed and discontinued in favor of better and cheaper techniques.
The contact method is currently used to produce concentrated sulfuric acid. It was developed in the 1800s by Peregrine Phillips, a British vinegar merchant. This method involves combining sulfur and oxygen and heating them. The material is then passed over the platinum or other catalyst before being passed through the towers where it is washed. The resulting product is a clear, highly concentrated product.
Concentrated sulfuric acid is used to make dyes and other products such as detergents, nitroglycerin and ether. This product is also used by oil refineries to remove impurities from gasoline and other products. The acid is used to clean the metal before a zinc or tin plating is added to it.
People who work with this chemical must observe specific safety precautions to avoid injury. Concentrated sulfuric acid is a highly corrosive material. Safety glasses, rubber gloves, and protective clothing must be worn to prevent the chemical from coming into contact with the eyes or skin. The higher the concentration, the more dangerous it is to work with the chemical.
Concentrated sulfuric acid can be diluted with industrial grade water. The exact concentration used will depend on the application for which the chemical is being used. For safety reasons, the acid should be added to a container of water when attempting to dilute it.
The solution of sulfuric acid and water must be stirred constantly to prevent a large amount of acid from settling at the bottom of the container. Concentrated sulfuric acid is heavier than water and will sink easily. The resulting mixture will be hot or boiling, and the combination of these two materials could result in a temperature that could be hot enough to boil water, which could lead to injury from sulfuric acid splashes.
