What is Hydrogen Sulfide? What are the Properties of Hydrogen Sulfide?

While the fight against the sea spittle, which is slowly killing the Sea of ​​Marmara, continues, another bad news came from the blue waters. Hydrogen sulfide, which could destroy new life, was encountered in the Çınarcık pit. So, what is hydrogen sulfide? What are the properties of hydrogen sulfide?

The last expedition of scientists, who have been looking for solutions to the sea saliva that has been under the influence of the Sea of ​​​​Marmara for 5 months, in the open sea was made with the Istanbul University Institute of Marine Sciences and Management, Turkey's largest and most equipped research ship Alemdar II. As a result of the research, hydrogen sulfide was found. So what is hydrogen sulfide? What are the properties of hydrogen sulfide?

WHAT IS HYDROGEN SULFIDE?

Hydrogen Sulfide Formula: H²S

• Boiling point : -60 °C
• Molar mass: 34,082 g/mol
• Density: 1,36 kg/m³
• Melting point: – 85,5 °C

Hydrogen sulfide is a colorless, poisonous gas with the odor of rotten eggs. The elements that make up the compound were determined by C. Louis Berthallet in 1796. Its formula is H2S.

The smell of hydrogen sulfide, which is a very strong poison, can also be felt at a concentration of 10-5. Liquefied hydrogen sulfide does not conduct electricity. Its boiling point is -60,75 °C, and its melting point is -83,70 °C. It is 1.19 times heavier than air. Its density at the boiling point is 0,993. It is highly soluble in water and alcohol. It is flammable. Air containing 4,5-45,5% hydrogen sulfide is explosive.

Small amounts of hydrogen sulfide are found in oil, hot springs, and natural gas wells. Hydrogen sulfide, which is also obtained from its elements, is obtained in laboratories by influencing hydrogen chloride on iron sulfide. Calcium or barium is formed by reacting sulfur to produce pure hydrogen sulfide.

In August 2015, hydrogen sulfide was discovered to be superconducting at -150 °C (1.5 °K) under very high pressure (70 GPa (203 million atm)). Hydrogen sulfide has the highest superconducting transformation temperature ever found.
