Observe the reactions of hydrogen sulfide with lead nitrate, silver nitrate and potassium manganate(VII) in this microscale practical. Includes kit list and safety instructions.

In this experiment, students react hydrogen sulfide with lead nitrate, silver nitrate and potassium manganate(VII) using microscale apparatus. They use a reaction vessel containing zinc sulfide and hydrochloric acid to generate the hydrogen sulfide gas inside a Petri dish, recording their observations as it reacts with the different test solutions.
