WebApr 9, 2024 · An example would be food with acidic ingredients like tomato sauce or lemon juice. With non-reactive pans like stainless steel, your food will not discolor or alter the pan’s appearance, and the pan will not break down. Nor will it change the taste of your food giving it a metallic taste. WebSelf-reactive chemicals are thermally unstable liquid or solid chemicals that can undergo exothermic decomposition without interacting with oxygen. Self-reactive chemicals can start decomposing due to: Heat. Contact with acids. Contact with heavy metal compounds. Contact with bases. Friction.
