Product (chemistry) facts for kids
A product in chemistry is the new substance that forms after a chemical reaction takes place. Think of it like baking a cake: you start with ingredients like flour and eggs (these are called reactants), and after you mix them and bake them, you get a cake. The cake is the product!
For example, when hydrogen ions (H+) combine with water (H2O), they create hydronium ions (H3O+). H+ + H2O → H3O+ In this reaction, H3O+ is the product.

What is a Chemical Reaction?
A chemical reaction is a process where atoms and molecules rearrange themselves to form new substances. It's like building with LEGOs: you take apart one creation and use the same bricks to build something completely different.
Reactants: The Starting Ingredients
Before a product can form, you need starting materials. These are called reactants. Reactants are the substances that are present at the beginning of a chemical reaction. They are the "ingredients" that will change.
For example, if you mix baking soda and vinegar, they are the reactants. They will react to create something new.
How Products Are Formed
During a chemical reaction, the bonds between atoms in the reactants break. Then, new bonds form, creating new arrangements of atoms. These new arrangements are the products.
It's not just mixing things together; it's a real change where new substances with different properties are made. Sometimes you can see these changes, like bubbles forming, a color change, or heat being released.
Examples of Products in Everyday Life
Chemical reactions and their products are all around us!
Rusting Metal
When iron metal (a reactant) reacts with oxygen from the air (another reactant), it forms rust. Rust is a new substance, and it's the product of this reaction. You can see it on old bikes or gates.
Burning Wood
When wood burns, it reacts with oxygen. The products of this reaction are ash, smoke (which contains carbon dioxide and other gases), and heat and light. The ash and gases are the chemical products.
Photosynthesis in Plants
Plants use a chemical reaction called photosynthesis to make their own food. They take carbon dioxide and water (reactants) and, with the help of sunlight, turn them into glucose (a sugar, which is a product) and oxygen (another product). This oxygen is what we breathe!
Digestion in Your Body
Inside your body, food goes through many chemical reactions. Large food molecules (reactants) are broken down into smaller molecules like sugars and amino acids (products). Your body then uses these products for energy and growth.
Why Are Products Important?
Understanding products is key to understanding chemistry. Scientists and engineers use this knowledge to create new materials, medicines, fuels, and many other things that improve our lives. For example, chemists can design reactions to produce specific medicines or plastics.
