selenium dioxide

Selenium dioxide is a chemical compound made from selenium and oxygen atoms. It appears as a yellow or reddish powder and is commonly used in laboratory and industrial processes. Chemically, it acts as an oxidizing agent, meaning it can help in the conversion of other substances by removing electrons. In organic chemistry, it is often used for oxidation reactions, such as transforming alcohols into aldehydes or ketones. Selenium dioxide must be handled with care because it is toxic and can be harmful if inhaled or ingested. Its applications are mainly in chemical synthesis and research rather than everyday products.
