A color change indicates the formation of a chemical change. This means a chemical reaction is occurring.
Is a change in color a chemical change?
Chemical changes are changes matter undergoes when it becomes new or different matter. To identify a chemical change look for signs such as color change, bubbling and fizzing, light production, smoke, and presence of heat.
When a chemical reaction occurs often there is a color change?
When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.

- Change of Temperature.
- Evolution of a gas (formation of bubbles)
- Precipitate (formation of a solid)
What’s the definition of unexpected color change?
Color changes are commonplace when substances are combined, but one of the identifying factors of a chemical reaction is an unexpected color change. For example, it would be expected that a blue and a yellow liquid would combine to produce a green liquid.
Why does a change in color indicate a chemical reaction?
Chemical Reactions. If you detect a change in the color of a material, why does this indicate that a chemical reaction might have occurred? Its the indication of a change in properties, and a change in properties is a sign that a chemical reaction occurred.
Seven Things That Indicate a Chemical Change Is Occurring. 1 Gas Bubbles Appear. Gas bubbles appear after a chemical reaction has occurred and the mixture becomes saturated with gas. The chemical change that 2 Formation of a Precipitate. 3 Color Change. 4 Temperature Change. 5 Production of Light.
When does the smell of a chemical compound change?
Change in Smell or Taste. Each chemical compound has its own distinct smell or taste. When the compound changes after a chemical reaction, the taste or smell of the compound changes as well.
What happens to energy when a chemical change occurs?
Production of Light. When energy is released due to a chemical change it sometimes creates a light source. This type of chemical reaction tends to occur in combustion reactions such as a fire or burning process.
