Can an egg float on salt water and why?
Yes, a raw egg will float if the salt concentration is high enough. This is possible because adding salt creates a solution with a greater density than water. As more salt is added, the density of the solution increases. At a certain point, the density of the solution becomes greater than the density of the raw egg, allowing the egg to float in the solution.*This experiment is a very good demonstration of the principle of buoyancy.
