-The egg sunk in the water, but floated on the saltwater.
You learned that the egg is denser than water (thus it sinks), but the egg is less dense than saltwater (therefore it floats).

Adding salt to the water makes the egg easier to peel.
The larger the salt concentration in the water, the more quickly the egg will achieve flotation. Adding salt to the water will cause the egg to float.
because salt increases the density of water so, egg ascend to top
An egg with an intact shell, warm water, a lot of table salt (NaCl), a suitable container to hold the above. Pour the (warm) water to the container, stir while adding salt to the water, keep adding salt until no more will dissolve (This is a saturated solution), allow to cool & gently place egg into the salt water.
Adding salt to the water increases its density. On adding certain quantity of salt, the density of water becomes greater than that of egg. So by law of flotation, as the mass of water (salted) displaced by egg is greater than its own mass, the egg floats.
This is because Salt adds density to the water. In other words, by adding and dissolving salt in the water, you make the water heavier than the egg.
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.

no you do not. But you can. A drop of vinegar helps!
as the salt dissolves in the water the water becomes more dense, so the egg will be more buoyant. (at least you tried to spell it correctly)
One method of determining if an egg floats in salt water is by dissolving salt in a container of water until the egg floats. Another method involves gradually adding salt to a container of water while placing the egg in to see if it floats. Both methods rely on the principle that the density of the water increases as salt is added, causing the egg to float when the water becomes dense enough.
The density of liquids really depends on the suspended matter in it. If you have really dense concentration of salt in water, yes it could be denser than an egg. If you have merely a weak solution of salt, then the egg is denser... it depend on how much salt you have in the water.
