Four drops of yellow food coloring are added to 10mL or water. The mixture is a pale yellow. Did a chemical take place? Explain completely your evidence for your answer, using of the scientific terms you have learned in this unit
In this case, a chemical reaction did not take place. The addition of four drops of yellow food coloring to water does not result in a chemical change. The mixture remains a pale yellow color, indicating that the food coloring molecules are simply dispersed in the water and not chemically altered.
When a chemical reaction occurs, the substances involved are transformed into entirely new substances with different chemical properties. In this case, the yellow food coloring molecules remain intact in the water and do not undergo any chemical changes.
Furthermore, the fact that the mixture is still a pale yellow color is evidence that no chemical reaction occurred. If a chemical reaction had taken place, the color of the mixture would likely have changed significantly as new substances were formed.
Therefore, based on the lack of a significant color change and the absence of new substances being formed, it can be concluded that no chemical reaction occurred when four drops of yellow food coloring were added to water.
