Product
A new substance formed as a result of a chemical reaction, appearing on the right side of a chemical equation, with different chemical properties from the original reactants. 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.
💡 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.
Formal View
🔬 Example
🎯 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.
⚠️ Common Confusion
Products can themselves become reactants in subsequent reactions.
How to Use Product
When this concept appears in chemistry, it usually controls how you interpret a representation, a quantity, or a change in a system. Students make faster progress when they can explain what product tells them before reaching for an equation or memorized phrase.
A strong self-check is to say what product does, what it does not do, and which nearby idea it is easiest to confuse with. That kind of explanation makes later calculations, lab reasoning, and compare pages much more reliable.
💭 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.
