Incompatible Chemicals: Acetylene Acetic Acid Activated Carbon Alkali Metals Aluminium Alkyls Ammonia Laboratory

This document lists incompatible chemicals that should be kept apart in a laboratory to avoid accidents. It provides examples of substances that may react violently if brought into contact, such as acetylene and chlorine, or acids and alkali metals. Due to the large number of hazardous materials, only the most important incompatible combinations are included as a guide. Proper storage and handling of chemicals is necessary to avoid dangerous reactions in the laboratory.
