Lead acetate sulfur test
Lead acetate is often used in the detection of sulfur, and its method is exquisite. Take the object to be tested and dispose of it in an appropriate manner. If it contains sulfur, it will change wonderfully when exposed to lead acetate.

Prepare the lead acetate solution carefully and pour it into the sample to be tested. If the sample contains sulfur elements, and the two meet, immediately, a black precipitate will slowly form. This is due to the chemical reaction between sulfur and lead acetate to form lead sulfide, and lead sulfide is black and easy to identify.

In this way, by looking at whether there is black precipitation, we can know whether the sample contains sulfur. This test method is quite practical, accurate and convenient when identifying whether a substance contains sulfur, which is of great benefit to the analysis and identification of substances.
