Color change Chemical reaction help

In summary, a color change chemical reaction is a reaction that causes a substance to change color, often due to a chemical change in the substances involved. This can be caused by factors such as pH, new compound formation, or the absorption/emission of light energy. Not all chemical reactions will result in a color change, but those that do have many useful applications in various industries.

I am working on a project that needs 2 chemicals to react and change colors. The catch is they most likely need to be or come in a powder form, non toxic, and relatively inexpensive.

PLEASE HELP!

To clarify: you want to mix two powders and observe color change?
 
  • #3
yes, that is correct
 
  • #4
...without heat

Try tumeric and methylene blue. Mix the yellow powder with the blue one and it turns green! How cool is that?
 

Related to Color change Chemical reaction help

1. What is a color change chemical reaction?

A color change chemical reaction is a reaction that causes a substance to change color. This can happen when two or more substances are mixed together, or when a substance is exposed to heat, light, or other external factors.

2. How does a color change chemical reaction work?

A color change chemical reaction works by causing a chemical change in the substances involved. This can happen when atoms or molecules in the substances rearrange themselves, creating new bonds and releasing or absorbing energy. This change in chemical structure can result in a change in color.

3. What causes a color change in a chemical reaction?

A color change in a chemical reaction can be caused by a variety of factors, such as a change in pH, the formation of a new compound with a different color, or the absorption or emission of light energy. It can also be caused by the presence of certain catalysts or the release of gases.

4. Can all chemical reactions result in a color change?

No, not all chemical reactions will result in a color change. Some reactions may result in a change in color, while others may not have any visible change at all. It depends on the specific substances and conditions involved in the reaction.

5. How can color change chemical reactions be useful?

Color change chemical reactions have a wide range of applications and uses. They can be used in the production of dyes and pigments, in forensic analysis, and in various industries such as food, cosmetics, and pharmaceuticals. They can also be used as indicators to monitor the progress of a reaction or to detect the presence of certain substances.
