Typically, the rate of oxidation can be slowed by:

Alligation is a mathematical method used for calculating the proportions of different concentrations in mixtures and is not related to chemical processes like oxidation. It does not influence the rate at which oxidation occurs; rather, it serves as a tool in pharmacology and chemistry for mixing solutions.

Distillation is a separation process used to purify liquids based on differences in boiling points. While it can remove impurities that may catalyze oxidation, it does not directly slow down the oxidation process itself. The primary purpose of distillation is not to inhibit reactions but to separate components.

Expiration refers to the end of the shelf life of a product, often due to spoilage or degradation. While expired products may be more prone to oxidation, this option does not actively slow oxidation; instead, it indicates that oxidation has likely already occurred or is inevitable once a product reaches its expiration date.
