A product is a substance that is formed as the result of a chemical reaction. Products are often what we want from a reaction, such as medicines in pharmaceutical synthesis, or what causes harm, like pollutants from combustion.
This concept is covered in depth in our chemistry terms and definitions guide, with worked examples, practice problems, and common mistakes.
Definition
A product is a substance that is formed as the result of a chemical reaction.
💡 Intuition
What you end up with after the reaction — the new stuff that gets made from the ingredients.
🎯 Core Idea
Products appear on the right side of a chemical equation and have different properties from reactants.
Example
Notation
Products appear to the right of the reaction arrow (\to). Coefficients before each formula indicate mole ratios. State symbols like (s), (l), (g), (aq) denote the physical state of each product.
🌟 Why It Matters
Products are often what we want from a reaction, such as medicines in pharmaceutical synthesis, or what causes harm, like pollutants from combustion. Predicting products is central to designing useful chemical processes.
💭 Hint When Stuck
When identifying products in a reaction, look at the right side of the arrow. First write out the balanced equation. Then identify every substance after the arrow — those are your products. Finally, verify that the products have different properties from the reactants.

🚧 Common Stuck Point
Products can themselves become reactants in subsequent reactions.
⚠️ Common Mistakes
- Confusing products with reactants — products are always on the right side of the arrow (\to), reactants on the left
- Forgetting that a catalyst is NOT a product even though it appears after the reaction — it was not newly formed
- Assuming products must be different elements than reactants — the same elements recombine into new compounds
