Reactivity of hydrogen peroxide

Hydrogen peroxide is a strange substance. It is somewhat similar to water but has completely different properties. For example, you should never try to put out a fire with hydrogen peroxide. Hydrogen peroxide can react as a powerful oxidizer in high concentrations. Unlike water, H2O2 is extremely reactive and breaks down easily. In the process,… Continue reading Reactivity of hydrogen peroxide

Industrial uses of sulfuric acid

Several millions of tons of sulfuric acid are produced annually. This compound is one of the most important raw materials in the chemical industry. Examples of usage are: Fertilizer industry Over 50% of the sulfuric acid is used here. When ammonia gas is introduced into sulfuric acid, ammonium sulfate (NH4)2SO4 is formed. The reaction of… Continue reading Industrial uses of sulfuric acid


The element sulfur is of great importance for chemistry, geochemistry, biochemistry, and environmental chemistry. It is worthwhile to learn more about this element and to deal with it in more detail. But there are other, not so scientific reasons: Nothing is so closely associated with alchemy as the properties of sulfur and its compounds. And… Continue reading Sulfur

Oxalic acid

Everyone knows sour-tasting plants. In the past, every child has at least tried some sorrel (Rumex acetosa) or some wood sorrel (Oxalis acetosella) in the forest. Everyone is surely familiar with the four-leaf oxalis forms such as Oxalis tetraphylla, which are sold as “lucky clover” on New Year’s Eve. They all have one acid in… Continue reading Oxalic acid
