Is adding food coloring to food a physical or chemical change?

Answer 1

Adding food coloring to a mixture would be considered a physical change. There are no new chemical bonds formed or broken. What you are creating is a new solution, just like adding salt to water and it dissolves. The salt stays salt, the water stays water. In this case what you are dissolving has a color to it so it changes the color of whatever you add it to but fundamentally the molecules that make up the food coloring stay the same.
