Chemical changes involve chemical reactions and the creation of new products. Typically, a chemical change is irreversible. In contrast, physical changes do not form new products and are reversible. This is a list of more than 10 examples of chemical changes.

  1. rusting of iron
  2. combustion (burning) of wood
  3. metabolism of food in the body
  4. mixing an acid and a base, such as hydrochloric acid (HCl) and sodium hydroxide (NaOH)
  1. cooking an egg
  2. digesting sugar with the amylase in saliva
  3. mixing baking soda and vinegar to produce carbon dioxide gas
  4. baking a cake
  5. electroplating a metal
  6. using a chemical battery
  7. the explosion of fireworks
  8. rotting bananas
  9. grilling a hamburger
  10. milk going sour

Need more? Chemical changes are the basis for chemical reactions. Here is a list of 10 chemical reactions in everyday life. Less-familiar chemical reactions are also examples of chemical changes. While it's not always easy to tell a chemical change has occurred, there are some telltale signs. Chemical changes may cause a substance to change color, change temperature, produce bubbles, or (in liquids) produce a precipitate. Chemical changes can also be considered to be any phenomenon that allows a scientist to measure chemical properties.

Understanding chemical changes is important, but it's helpful to understand them in the context of physical changes.
