This week we've been doing a diffusion/osmosis lab involving chicken eggs. Day one our eggs spent 24 hrs in vinegar, which dissolved the calcium carbonate shell. After spending another 24 hrs in distilled water the water diffused through the egg's membrane (osmosis), making the egg a little more plump. Today we removed the water and added a coating of thick corn syrup to the plump eggs. What do you think will happen by tomorrow morning??
