Some indicators include:
- Change in Temperature
- Change in Color
- Noticeable Odor (after reaction has begun)
- Formation of a Precipitate
- Formation of Bubbles
When two or more reactants are mixed and a change in temperature, color, etc. is noticed, a chemical reaction is probably occurring. These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical. This is because the composition of the car has not changed. Proceed with caution.
