Food colouring is a mixture .and you separate it using chromatography
Once the food coloring completely colors the water, yes. It is homogeneous because the mixture, a solution, has the same composition throughout.
YES
Yes. There is no harm in drinking water with food coloring. Food coloring is made to be consumed, whether with water, cake icing, or other foods.
When an egg is boiled, the water interacts with the eggshell causing it to become porous. As a result, food coloring can seep through the shell and form a compound on the egg's surface. The coloring binds to the proteins in the egg white as it cooks, creating a stained effect.
Only if the food coloring is itself acidic.
you don't have to put water in food coloring you can put it in icing or cake batter
No, food Coloring is a water based dye, it will have a negligible effect on the rate at which water evaporates.
The food coloring formed a compound on the surface of the egg due to the high concentration of dye coloring in the dye solution and the porous nature of the eggshell. When the dye solution was in contact with the egg, the coloring molecules were able to penetrate the eggshell and bind to the proteins in the egg white, resulting in the coloring compound formation on the surface of the egg.
yes you can cause its just a food coloring
food coloring is made up of many substances such as water and dye. The color of the dye is the color of food coloring.
When you put a drop of food coloring into a glass of water, the water will turn that color.
Physical, the water is still water and the food coloring is still food coloring you just mixed them together in one space. If you waited long enough the food coloring and water would settle back out so you had just water and food coloring.
