Testing For Hydrogen Sulfide
The method of detecting hydrogen sulfide
To find out whether there is hydrogen sulfide in the object, you can test it according to the following method.
Use a clean glass sheet to coat it with a thin and uniform lead acetate test solution. Apply the glass sheet of the coating solution to the object to be tested. If there is hydrogen sulfide in the object, in a moment, the place where the liquid is coated on the glass sheet will be brown and black. This is because hydrogen sulfide and lead acetate are combined, and the raw brown-black lead sulfide is also.
Or use a moist blue litmus test paper near the object. If the test paper turns red and smells rotten eggs, it can also be a sign of hydrogen sulfide. The aqueous solution of hydrogen sulfide is acidic, which can turn blue litmus paper red, and it has the stench of rotten eggs.
All these are common methods for detecting hydrogen sulfide. According to this operation, it can be determined whether there is hydrogen sulfide in the product.
