It increases.
Salt will increase the density of water at the same temperatures.
density
the salt makes seawater denser than freshwater. more salt increases the density
The temperature of the water and the salt content of the water.
salt water is different from tap water. when salt is added to water it converts the tap water to salt water. This increases the density of the water, and allows more objects to float above it. remember, when objects are mixed like that, the greater the density, the further it is from the surface.
In aspect of egg floated in salt water is no, egg didn't change it's density just salted water is more dense. In the aspect of salted egg (marinaded in salted water for a week) is yes. Diffused salt content would increase the density of the egg.
No salt has a greater density.
Salt water density really depends on a few different things. The concentration of salt and temperature are the 2 largest factors in determining the density of salt water.

The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
Yes, fresh water has a slightly lower density than salt water.
