oxidation reactions

Oxidation reactions involve a substance losing electrons, often resulting in a change in its chemical state. This process typically happens when a substance reacts with oxygen, like when iron rusts, or when it interacts with other oxidizers. Oxidation can release energy, as in combustion, or alter the properties of materials, such as browning in apples. Essentially, it's a chemical transformation where electrons are transferred away, altering the original substance’s composition and often leading to new compounds or effects.
