What is hydrosulfuric acid?
hydrosulfuric acid is a highly toxic chemical compound that is performed when the hydrogen sulphide is dissolved in water. The strongest distinguishing feature of hydrosulfuric acid is classified as a weak acid, its strong fragrance, reminiscent of rotten eggs, giving it the nicknames of "stinking wet" and "sewer gas". It is in large quantities in the Earth's crust and also known as sulfuric acid, it is not only a large part of volcanic emissions, but is also present in many fossil fuels, including oil and natural gas. Although both contain hydrogen and sulfur, hydrosulfuric acid is very different chemicals from sulfuric acid. Each of its molecules contains two hydrogen atoms and one sulfur atom, giving it a molecular weight of 34.08. The acid itself is considered to be relatively weak, especially in comparison with sulfuric acid. While pH sulfuric acid is extremely low 1.0, pH hydrosulfuric acid is4.5, the introduction of its relative strength somewhere between bananas and tomato juice.
Sulfate is present in many fossil fuels. In fact, one of the simplest ways to produce it is simply to separate it from "acid gas", a natural gas that is falsified up to 90 % of the hydrogen sulphide. Although it is less prevailing in raw oil, it is often present. Its presence in the well in the form of sulfuric acid can be dangerous, which requires to be oxidized by ozone or manganese filter to be inert and non -toxic.
sulphhydric acid is not often produced or strongly used chemicals compared to other acids due to limited number of applications. Although this can be done by a process involving the combustion of elemental sulfur with hydrogen, hydrosulfuric acid may also be turned back to the elementary sulfur. Chemists also use it as an analytical tool to detect the presence of metal elements in solutions. Other applications include its use to departureHeavy water, a type of water made of deuterium instead of hydrogen, which is useful in certain nuclear reactors, from regular water.
as toxic as cyanide, hydrosulfuric acid is dangerous chemicals, especially in its gaseous form. One of its most dangerous characteristics is that it has a strong and unpleasant odor in harmless low concentrations, but shrinks a pure feeling in higher, toxic concentrations. In the First World War, the British used it as an agent of a chemical war and in 2008 participated in suicide cluster in Japan. Some paleontologists think that at the end of the permical period he played a major role in mass extinction, approximately 250 million years ago.
