Question 38

Multiple Choice

Silver tarnish (Ag2S) can be removed by immersing silverware in a hot solution of baking soda (NaHCO3) in a pan lined with aluminum foil; however, foul-smelling hydrogen sulfide gas (H2S) is produced.Which one of the following reactions does NOT represent part or all of what is happening?  Silver tarnish (Ag<sub>2</sub>S)  can be removed by immersing silverware in a hot solution of baking soda (NaHCO<sub>3</sub>)  in a pan lined with aluminum foil; however, foul-smelling hydrogen sulfide gas (H<sub>2</sub>S)  is produced.Which one of the following reactions does NOT represent part or all of what is happening?
