Answer:
Making soap can be considered a chemical reaction.
Step-by-step explanation:
In the process of making soap, a reaction takes place between a fat or oil and an alkali, such as lye (sodium hydroxide), which results in the formation of soap molecules and glycerol. This reaction is known as saponification. The change in the composition of the reactants to form a new substance is a chemical change, not a physical change or a phase change.
