Dding bleach to red food coloring causes the food coloring to lose its color. is this a physical or chemical change? explain.

chemical change

Explanation:

Some evidence for recognizing a chemical change is: effervescence, precipitate, color change, appearance of light, and heat transfer. For this reason, we can say that the answer to your question is "Chemical Change".

One of the main characteristics of a chemical change is the color change. This chemical change is usually the result of reactions in which there is electron transfer (oxirreduction), with the formation of cations that provide the characteristic color. For example, an aqueous solution of copper sulfate II is blue because it has copper (Cu2 +) cations. Another example is the burning of fireworks, which uses salts of different cations to give the colored effect that is seen.

Color-changing chemical transformations can be seen in many cases, such as fruit rotting, bleach on colored tissue, burning paper, cooking food, when tree leaves dry and rusting nails.
