Sulphur residue is the byproduct that remains after pure sulphur has been burned. It is a yellowish substance that may appear as a powder or solid material.
Pure sulphur can be burned by heating it to its melting point of 115°C, which causes it to ignite and produce a blue flame. It can also be burned by mixing it with an oxidizing agent, such as potassium nitrate, and igniting the mixture.
Burning pure sulphur is often done as a method of purification, as it can help remove impurities from certain substances. It is also used in various industrial processes, such as producing sulfuric acid.
Sulphur residue is not considered hazardous, as it is a non-toxic substance. However, it may irritate the skin, eyes, and respiratory system if inhaled or touched in large quantities. It is important to handle and dispose of it properly.
Sulphur residue can be disposed of by mixing it with water to create a slurry and then pouring it down the drain. It can also be safely disposed of in a landfill. However, it is important to check with local regulations for proper disposal methods.
