How does an salt make an egg float?

Answer 1

The separate layers formed because salt water is denser than pure water. Fresh water has a density of about 1.0 gram per ml of volume. Matter with higher density will sink in water; matter with lower density will float on top.The density of an egg is between that of water and salt water, so in your beaker, the egg balanced between the two layers.

Answer 2

When you add salt to water, it increases the density of the water. This increased density reduces the overall density of the egg, making it float because objects with lower density than the surrounding liquid will float.

Answer 3

Any object that sinks in a liquid has to be more dense than the liquid. An egg has slightly higher density than fresh water, so it will sink. When you dissolve salt in the water the density of the resulting saline solution increases past that of the egg, so the egg begins to float.

Answer 4

the salinity or how much salt is it the water because the salt is more dense then the egg so the egg then floats.

another thing it might be is that the egg has an air pocket which makes it float in water like a water balloon

i hope i have answered your question

Answer 5

Mixing the water with salt can cause it to become more dense than the egg, so the egg will float.

Answer 6

Salt makes an egg float when it's in water because the salt dissolves so it makes the water thicker which allows the egg to float.

Answer 7

Salt water has a greater density than pure water.
