How To Get Hydrogen Sulfide
The method of obtaining hydrogen sulfide
To obtain hydrogen sulfide, there are two methods. First, mix ferrous sulfide with dilute sulfuric acid. Put ferrous sulfide in a flask and slowly inject dilute sulfuric acid, and the two will react immediately. The reason for the reaction is that when ferrous sulfide encounters dilute sulfuric acid, sulfur ions combine with hydrogen ions to produce hydrogen sulfide gas. This reaction is smooth and easy to collect. When collecting, you can use the method of upward exhaust air, and the density of hydrogen sulfide is higher than that of air. And hydrogen sulfide smells like rotten eggs, which is highly toxic. When operating, it should be well ventilated to avoid poisoning.
Second, if sulfur and hydrogen are co-heated, hydrogen sulfide can also be obtained. The reaction of sulfur and hydrogen requires high temperature conditions and is a reversible reaction. To make the reaction proceed in the direction of generating hydrogen sulfide, it is necessary to increase the amount of hydrogen and control the temperature. This reaction is carried out in a closed container. When collecting the product, it is necessary to take into account the unreacted sulfur and hydrogen. After collection, the residual gas should also be properly disposed of to prevent pollution to the environment.
All hydrogen sulfide must be handled with caution and heavy safety protection to ensure safety.
