Hydrosulfuric acid formula

Hydrosulfuric acid formula

The hydro- prefix means that it contains hydrogen. The “sulfuric” means that it contains sulfur. Since Hydrogen has a charge of +1 and Sulfur has a charge of -2, there have to be 2 Hydrogen atoms to make the compound have a neutral charge.

Therefore the formula is: H2S (aq)
Molar Mass: 34.0809
Other Chemical Names: Hydrogen sulfide; Sulfur; Hydrosulfuric acid; Stink DAMP; Sulfane; Sulfureted hydrogen;

H2S is a colorless gas at room temperature. Its melting point is -82 ̊C (-115.6 ̊F), boiling point -60 ̊C (-76 ̊F), density 0.00136 g/cm3. H2S has an odor of rotten eggs. It is toxic, corrosive and flammable.

The (aq) stands for aqueous and means that it is dissolved in water and therefore an acid. It should be in subscript, just like the 2.
