H2S is a colorless gas. 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.
Example Reactions:
• FeS + 2HCl = FeCl2 + H2S
• H2SO4 + 8HI = H2S + 4I2 + 4H2O
• Co(NO3)2 + H2S = CoS + 2HNO3
• H2S + 4Na2O2 + 2H2O = Na2SO4 + 6NaOH
• H2S + 2AgNO3 = Ag2S + 2HNO3
• ZnS + 2HCl = ZnCl2 + H2S
• H2S + CuCl2 = CuS + 2HCl
• H2S + 2KOH = 2H2O + K2S
• H2S + HgCl2 = HgS + 2HCl
• Na2S + 2HCl = 2NaCl + H2S
