H2S Alive Ontario!


H2S Alive Toronto – Hydrogen sulfide is the chemical compound which has the formula of H2S. Hydrogen sulfide has the characteristic foul odor of rotten eggs and is a flammable, colorless and really poisonous gas. The smell is caused by the bacterial breakdown of organic matter that is in the absence of oxygen, such, as in sewers and swamps. This process is known as anaerobic digestion. The process with hydrogen sulfide happens in volcanic gases, in in natural gas and some well water. H2S is used by the human body as a signaling molecule and generates small amounts.

Hydrogen sulfide is a bit heavier than air. Thus, a mixture of air and H2S could be explosive. Hydrogen sulfide and oxygen burns with a blue flame and becomes sulfur dioxide or SO2 and water. Normally, H2S acts as a reducing agent within chemical reactions.

Sulfur dioxide, with the presence of catalysts or at high temperature, can form water and elemental sulfur when it reacts with hydrogen sulfide. This process is defined in the most common way to convert H2S into elemental sulfur, the Claus process.

Hydrogen sulfide is somewhat soluble in water. It acts as a weak acid and therefore gives the hydrosulfide ion “HS-.” Hydrosulfuric acid or sulfhydric acid is a solution of hydrogen sulfide in water. Initially, this type of solution is initially clear but turns cloudy eventually. This is caused by the slow reaction of hydrogen sulfide with the oxygen dissolved in water. This reaction yields elemental sulfur that precipitates out. The sulfide dianion S2- just exists in strong alkaline aqueous solutions. Usually this substance is basic with a pKa>14.

Hydrogen sulfide reacts with metal ions. When this happens, metal sulfides are formed and these may be considered the salts of hydrogen sulfide. For example, some types of ores are sulfides. Often, metal sulfides are dark colored. Lead II acetate paper is used in the detection of hydrogen sulfide. In the presence of the gas it turns grey when lead II sulfide is made. Hydrogen sulfide is liberated by reacting metal sulfides with strong acid.

It is essential to recognize that if gaseous hydrogen sulfide comes into contact with concentrated nitric acid, an explosion occurs. In addition, when alcohols reacts with hydrogen sulfide, it forms thiols
