"Lead Acetate Test"

For lead acetate testers, the method of detecting sulfur in substances is also used. The method is to encounter the lead acetate solution with the object to be tested. If there is sulfur present, it will produce black lead sulfide precipitation.

Anyone who wants to know whether something contains sulfur or not, often try this method. First take an appropriate amount of the liquid to be tested, put it in a clean container, and drop a few drops of the lead acetate solution. If the solution gradually produces black or brown precipitation, this is a sign of sulfur content. When the sulfur ion meets the lead ion, it synthesizes lead sulfide, which is black in color and easy to identify.

It is also important to pay attention to this method. First, other things may disturb it, resulting in inaccurate results. Such as some metal ions, or the reaction with lead acetate, similar to the reaction phenomenon of sulfur. Therefore, before use, it is advisable to remove impurities to make the liquid to be tested pure. Second, lead acetate is toxic, so be careful not to let it touch the body, especially avoid the entrance. After use, properly dispose of it, and do not pollute the environment.

Lead acetate test is simple and effective in sulfur evolution. When using it, you should follow the law and pay attention to all ends to obtain accurate results.
