Other names: D, Ihydrogen monosulfide|Dihydrogen sulfide|Sewer gas|Sulfane|Sulfurated hydrogen|Sulfureted hydrogen|Sulfuretted hydrogen|Sulfur hydride|Hydrosulfuric acid|Hydrothionic acid ...
Sodium sulfide is a chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S·9H 2 O. Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a ...
A chemical equation represents a chemical reaction. It shows the reactants (substances that start a reaction) and products (substances formed by the reaction). For example, in the reaction of hydrogen (H₂) with oxygen (O₂) to form water (H₂O), the chemical equation is: H 2 + O 2 = H 2 O.
Na2S + H2O = H2S + NaOH is a Double Displacement (Metathesis) reaction where one mole of aqueous Sodium Sulfide [Na 2 S] and two moles of liquid Water [H 2 O] react to form one mole of solid Hydrogen Sulfide [H 2 S] and two moles of aqueous Sodium Hydroxide [NaOH]
