What is an oxidizer commonly characterized by?

An oxidizer is commonly characterized by its ability to provide oxygen-rich compounds that facilitate combustion. In various chemical reactions, particularly in pyrotechnics and explosives, oxidizers play a crucial role by supplying the necessary oxygen to support the burning of fuel materials. This reaction is essential for the production of the bright colors and loud sounds associated with fireworks and special effects.

In contrast, materials that decompose to release heat or remain stable at high temperatures may not function as oxidizers. Additionally, stating that an oxidizer cannot be used in pyrotechnics is misleading, as oxidizers are fundamental components of many pyrotechnic formulations. The specific characteristic of providing an abundant supply of oxygen is what sets oxidizers apart in their functional role in combustion processes.
