Reactant

Imagine you’re preparing a meal and you start with a raw potato. Just like the potato changes when you cook it, turning from hard and starchy to soft and edible, a reactant in a chemical reaction is a substance that is transformed into a different substance. In this analogy, the potato is like the reactant because both undergo a change in their structure or composition to become something new and useful, whether it’s a cooked dish or a new chemical product.
