We did an experiment on osmosis by putting a potato in fresh an salt water. We noticed that the potato in the salt water lost mass and concluded that water left the cells. the opposite was true for the fresh water potato, it gained mass. We predicted that if food coloring was added to the salt water and fresh water containers, the coloring would enter the fresh water potato and not enter the salt water. The opposite happened. The salt water potato absorbed the food coloring and the fresh water potato didn't. Could be because of diffusion but not sure.
Re: Why does food coloring enter a potato in salt water?
